A simple and inexpensive laser power meter
Ferguson,A

J. Phys. E: Sci. Instrum.
Vol.17(3) 1984 pp.189-
DOI:10.1088/0022-3735/17/3/004

Abstract

The construction of a simple and inexpensive laser power meter is described. The laser power is monitored using a calorimeter sensor which is based on the use of commercial platinum resistors. In this design, the use of volume absorbing glass enables the meter to withstand peak power densities in the region of 100 MW cm-2 and average powers in excess of 10 W at 1.06 mu m. Average powers down to less than 1 mW can also be readily measured.



Dual-Purpose, Compact Spectrometer and Fiber-Coupled Laser Wavemeter Based on a Wollaston Prism

Applied Optics
Vol.37(24) 1998 pp.5777-5778
DOI: 10.1364/AO.37.005777

Abstract

A fiber-coupled, compact laser wavemeter based on a modified Wollaston prism has been constructed and evaluated. The path difference between orthogonal polarization states of the input light varies smoothly across the aperture of the prism forming an interferogram in the spatial domain that is recorded with a CCD detector array. A Fourier transform of this interferogram gives the spectral distribution of the incident light. Alternatively, for a narrow-linewidth source a fringe period measurement technique is used to obtain precision measurement of the center wavelength. Using 752 interferogram data points we obtain a wavelength precision of 1 part in 106. The elimination of moving parts from the design makes the recorded interferogram inherently stable.


Design of a static Fourier-transform spectrometer with increased field of View

Courtial,J;Patterson,B;Harvey,A;Sibbett,W;Padgett,M

Applied Optics
Vol.35(34) 1996 pp.6698-6702
DOI: 10.1364/AO.35.006698

Abstract

We present several novel designs of static Fourier-transform spectrometers based on Wollaston prisms. By numerical modeling we show the increased field of view that can be obtained when an achromatic half-wave plate is included between the prisms or when prisms fabricated from positive and negative birefringent materials are combined. In addition, we model how a single Wollaston prism with an inclined optic axis produces a fringe plane localized behind its exit face, thus enabling the design of a static Fourier-transform spectrometer based on a single Wollaston prism.[/url]


Analysis and Design of Compact, Static Fourier-Transform Spectrometers

Montarou,Carole;Gaylord,Thomas

Applied Optics
Vol.39(31) 2000 pp.5762-5767
DOI: 10.1364/AO.39.005762

Abstract

A new, to our knowledge, analytical method is presented to characterize the performance of modified-Wollaston-prism-based compact, static Fourier-transform spectrometers. With the aid of an exact ray-tracing method for birefringent media, the interference of the two wave fronts produced by the beam splitter is computed at an arbitrarily positioned detector array. It is shown that a compact, static Fourier-transform spectrometer employing a single modified Wollaston prism can be designed such that the fringes are perpendicular to the incident beam. The effects of aperture size, coherence of the source, and incidence angle on the resulting interferogram are quantified.


Highly accurate laser wavelength meter based on Doppler effect

Wakim,M;Topcu,S;Chassagne,L;Nasser,J;Alayli,Y;Juncar,P

Optics Communications
Vol.262(1) 2006 pp.97-102
DOI: 10.1016/j.optcom.2005.12.049

Abstract

We have built an accurate wavelength meter based on a Michelson interferometer characterized by a high stability velocity moving system. The unknown wavelength is determined from the Doppler frequency shifts of the output beams of the Michelson interferometer. The reference laser is a frequency stabilized helium–neon laser. A counting resolution of 2.6 × 10?9 for an integration time of 30 s has been obtained. The apparatus has been used to determine the wavelength of a second frequency stabilized helium–neon laser and the result has been compared to those given by two different methods: frequency beating in regards to the national reference and using a commercially available scanning-Michelson wavemeter. Taking into account the statistical errors, we achieved a relative accuracy on the unknown wavelength of 6.4 × 10?8 at 1?.


Low-cost wavemeter with a solid Fizeau interferometer and fiber-optic input

Faust,Benedikt;Klynning,Lennart

Applied Optics
Vol.30(36) 1991 pp.5254-5259
DOI: 10.1364/AO.30.005254

Abstract

A wavemeter suitable for measuring the wavelength of pulsed and continuous laser light has been constructed on the basis of a solid Fizeau interferometer (SFI). An accuracy of 1 part in 106 has been demonstrated in a range extending from 563 to 613 nm. The use of the SFI and of a combination of a single-mode optical fiber and an achromatic lens as a beam collimating system substantially simplifies the optical layout and reduces cost. The difficulties connected with the dispersion of the SFI have been overcome by an analytical description of the characteristics of the interferometer and accurate temperature stabilization.


Calibration of a Computer-Controlled Precision Wavemeter for Use with Pulsed Lasers

Bhatia,Parminder;McCluskey,Craig,Keto,John

Applied Optics
Vol.38(12) 1999 pp.2486-2498
DOI: 10.1364/AO.38.002486

Abstract

The design of a pulsed wavemeter to monitor the high-precision tuning of pulsed (as well as cw) laser sources is presented. This device is developed from a combination of silver-coated Fabry–Perot etalons with various plate spacings. These etalons provide stepwise refinement of the wavelength to be measured. The wavemeter is controlled by a computer through a CAMAC interface, which measures the absolute wavelength in the visible with an accuracy of 2 parts in 108. The time required for data acquisition and computation to measure the refined wavelength with a single 2-MHz CPU is less than 100 ms. We describe the calibration of the instrument over the wavelength range 400–850 nm. We obtain the required calibration lines by locking lasers on hyperfine transitions of iodine, uranium, rubidium, and cesium. Methods to reduce the number of calibration lines required for calibration of the system are described. The expected wavelength-dependent phase shift of the silver coatings is compared with that measured for the etalon following calibration. The differences are larger than expected because of either optical aberations or the use of centroids to measure the fringe position.


Laser wavemeter with solid Fizeau wedge interferometer

Reiser,Christopher;Lopert,R

Applied Optics
Vol.27(17) 1988 pp.3656-3660
DOI: 10.1364/AO.27.003656

Abstract

A Fizeau wavemeter using a solid Fizeau wedge interferometer that is suitable for determining the wavelength of pulsed or cw laser light has been modeled and investigated experimentally. Accuracy of a few parts in 106 over a wide wavelength range can be achieved with careful design. Experimental accuracy of 2 parts in 106 was demonstrated over a range of 40 nm.


Compact Fizeau wavemeter

Gardner,James

Applied Optics
Vol.24(21) 1985 pp.3570-3573
DOI: 10.1364/AO.24.003570

Abstract

A Fizeau wavemeter using a sealed airspaced wedge is described. Off-axis geometry is employed to produce a compact instrument with good temperature stability. Calibration using a cw multimode dye laser and an argon discharge lamp is described. A precision of 2 in 107 and an accuracy better than 2 in 106 have been achieved.


Differential Wavelength Meter for Laser Tuning

Howard,Lowell;Stone,Jack

Rev. Sci. Instrum.
Vol.68(4) 1997 pp.1648-1651
DOI: 10.1063/1.1147971

Abstract

A simple interferometer for matching the wavelengths of tunable lasers is described. Our interferometer uses the angular dispersion of a diffraction grating at the Littrow angle to produce a tilted wavefront with respect to a reference mirror in an opposing arm of a Michelson interferometer. As a first step, the resulting interference pattern is adjusted to produce a null fringe using a reference laser as a wavelength standard. When a tunable laser, such as a laser diode, is used to illuminate the system, the laser is simply tuned to reproduce the null fringe pattern established using the reference laser. When so tuned, the wavelength of the tunable laser is matched to that of the reference laser within about 3 GHz, close enough for optical heterodyning.

Single-pulse, Fourier-transform spectrometer having no moving parts

Padgett,M;Harvey,A;Duncan,A;Sibbett,W

Applied Optics
Vol.33(25) 1994 pp.6035-6040
DOI: 10.1364/AO.33.006035

Abstract

A Wollaston prism is used in the design of a polarizing Fourier-transform spectrometer with no moving parts. The effective path difference between orthogonally polarized components varies across the aperture of the instrument, forming an interferogram in the spatial rather than temporal domain. The use of a charge-integrating linear detector array permits the entire interferogram to be sampled simultaneously so that a full spectrum is obtained for a single pulse of light.


Static Fourier-Transform Spectrometer with Spherical Reflectors

Zhan,Gao

Applied Optics
Vol.41(3) 2002 pp.560-563
DOI: 10.1364/AO.41.000560

Abstract

A compact reflection Fourier-transform spectrometer without moving parts is developed. The spectrometer consists of two spherical reflectors: a Sagnac interferometer and a linear detector. The developed system is as small as 202 mm long × 185 mm wide × 100 mm high. The optics and the system configuration are described, and the preliminary experimental results are shown.


Simple compact Fizeau wavemeter

Gray,D;Smith,K;Dunning,F

Applied Optics
Vol.25(.8.) 1986 pp.1339-1343
DOI: 10.1364/AO.25.001339

Abstract

A relatively simple, inexpensive, and compact Fizeau wavemeter is described that provides an accuracy of better than 1 part in 106  across the visible spectrum. The design is a variant of that initially proposed by Gardner and employs a novel geometry to eliminate wavelength measurement errors due to changes in wave front curvature.

Steam-Explosion Lignins: Fractionation, Composition, Structure and Extractives

doi:10.1016/j.biortech.2008.12.004

Abstract

In the present study, a steam explosion wood pre-treatment process, optimized earlier with respect to ethanol production, has been applied to both softwoods (Picea abies and Pinus sylvestris) and hardwoods (Betula verrucosa and Populus tremula). The alkaline extractable lignins have then been isolated to investigate lignin separation efficiency and lignin structure and to evaluate their potential for producing value-added products, such as biodiesel components or chemicals, in terms of the purity, molecular size, functional groups, ?-O-4? inter-unit linkage content, and degradability in a subsequent processing treatment. The mechanism of lignin modification and possible improvements to the steam explosion pre-treatment process are discussed.



Recent progress in the understanding of steam explosions

a Department of Chemical and Nuclear Engineering, University of California at Santa Barbara, Santa Barbara, CA 93106, USA

Abstract

If a hot liquid contacts a cold volatile liquid, a violent explosion may result. Such explosions are physical in character and involve a complex sequence of events. Initially, the liquids mix on a coarse scale and the system is relatively quiescent. However, if a suitable triggering event occurs, a violent shock-driven propagation can follow, which results in the generation of very high pressures and damage to surrounding structures. In this paper, we present a brief description of the various industries affected by such explosions and describe the underlying sequence of events which leads to these explosions. We then summarize the recent progress which has been made in this area and describe a new initiative which we believe will benefit all those with an interest in this phenomenon.

bDepartment of Community, Occupational and Family Medicine, National University of Singapore, 16 Medical Drive, Singapore 117597, Singapore

Abstract

Surfactant assisted pressurized liquid extraction (PLE) with a laboratory made system was applied for the extraction of glycyrrhizin in Radix glycyrrhizae/liquorice and ephedrine in Ephedra sinica. The proposed system set-up for this current work was simpler as no heating and back pressure regulator was required. Extraction with surfactant assisted PLE was carried out dynamically at a flow of 1.5 mL min?1, at room temperature, under an applied pressure of 10–20 bar with an extraction time of 45–50 min. The extraction efficiencies of the proposed method using surfactants such as sodium dodecyl sulfate (SDS) and Triton X-100 were compared with sonication using organic solvent for different batches of medicinal plants materials. For the determination of glycyrrhizin in R. glycyrrhizae, the extraction efficiencies of surfactant assisted PLE with SDS and Triton X-100 was observed to be comparable with sonication. The method precision was found to vary from 1.6 to 2.6% (R.S.D., n = 6) on different days. For ephedrine in E. sinica, surfactant assisted PLE with SDS was found to give higher extraction efficiencies compared to Triton X-100. The overall method precision for surfactant assisted PLE with SDS for ephedrine in E. sinica was found to vary from 1.5 to 4.1% (R.S.D., n = 6) on different days. The marker compounds present in the various medicinal plant extracts were determined by gradient elution HPLC. Our data showed the possibility of PLE at room temperature and the advantages of eliminating the use of organic solvents in the extraction process.

Mechanism of the Photocatalytic Oxidation of Ethanol on TiO2
Darrin S. Muggli, Justin T. McCue and John L. Falconer
Journal of Catalysis 1998, 173(2): 470 DOI: 10.1006/jcat.1997.1946

Abstract
Transient, isothermal photocatalytic oxidation (PCO) was combined with isotope labeling and temperature-programmed desorption and oxidation to directly identify reaction pathways and intermediates for the room-temperature PCO of ethanol on TiO2. The intermediates identified are acetaldehyde, acetic acid (acetate), formaldehyde, and formic acid (formate). The ?-carbons of ethanol, acetaldehyde, and acetic acid were labeled with13C so that the reaction pathway of each carbon could be followed. For each molecule, the ?-carbon preferentially oxidized to CO2as the two-carbon species were sequentially oxidized. Ethanol forms acetaldehyde, which either desorbs or oxidizes through at least two parallel pathways, only one of which involves acetic acid. Part of the ethanol reacts on the surface through the pathway: acetaldehyde ? acetic acid ? CO2+formaldehyde ? formic acid ? CO2. The remaining ethanol oxidizes more slowly through a pathway that does not contain acetic acid as an intermediate: acetaldehyde ? formic acid+formaldehyde ? formic acid ? CO2. The oxidation of ethanol to acetaldehyde is not the rate-determining step. The oxidations of formaldehyde to formic acid, and formic acid to CO2, occur at about the same rate, which is faster than acetic acid oxidation. Acetaldehyde oxidizes to form intermediates at approximately the same rate as they are oxidized. The presence of acetaldehyde on the surface, however, decreases the reactivity of other intermediates, suggesting that increasing the rate of acetaldehyde oxidation would increase the overall rate of CO2production.

High nonlinear optical anisotropy of urea nanofibers

Isakov et al

Euro Phys. Let.
Vol.91(2) 2010 28007

DOI: 10.1209/0295-5075/91/28007


Abstract

Nanofibers consisting of the optically nonlinear organic molecule urea embedded in both poly(ethylene oxide) (PEO) and poly(vinyl alcohol) (PVA) polymers were produced by the electrospinning technique. The second-harmonic generation produced by aligned fiber mats of these materials displays a strong dependence on the polarization of the incident light. In PVA-urea nanofibers the effectiveness in generating of the second-harmonic light is as high as that of a pure urea powder with an average grain size of 110 ?m. The results suggest that single crystalline urea nanofibers were achieved with a long-range crystalline order extending into the range of 2–4 ?m with PVA as the host polymer.

A Powder Technique for the Evaluation of Nonlinear Optical Materials

Kurtz,S;Perry,T

J. App. Phys.
Vol.39(8 ) 1968 3798-3813
DOI: 10.1063/1.1656857  

Abstract

An experimental technique using powders is described which permits the rapid classification of materials according to (a) magnitude of nonlinear optical coefficients relative to a crystalline quartz standard and (b) existence or absence of phase matching direction(s) for second?harmonic generation. Results are presented for a large number of inorganic and organic substances including single?crystal data on phase?matched second?harmonic generation in HIO3, KNbO3, PbTiO3, LiClO4·3H2O, and CO(NH2)2. Iodic acid (HIO3) has a nonlinear coefficient d14?1.5×d31  LiNbO3. Since it is readily grown from water solution and does not exhibit optical damage effects, this material should be useful for nonlinear device applications.

Designing an ignitor for short-arc xenon lamps

Moo,C;Lin,T;Chuang,Y

34th Annual IAS Meeting
Conf. Record. 1999 IEEE Meeting Vol.1 1968 pp.612-617
DOI: 10.1109/IAS.1999.800015

Abstract

A compact ignitor is designed for short-arc xenon lamps which require high ignition voltage and fast transition. The ignitor employs two stages of step-up circuits with two small sized transformers. A capacitor with an intermediate voltage is used for storing the energy converted from the DC power supply by the first-stage step-up circuit. The impact voltage necessary for igniting the xenon lamp is generated by the second-stage step-up circuit which is connected in series with the lamp and the DC power supply. The design of the ignitor for a short-arc xenon lamp of 350 W is discussed as an illustrative example

Luminescent Properties of Sodium Salicylate Films Prepared by the Sol?Gel Method
Ramaos,G;delMonte,F;Zurro,B;McCarthy,K;Baciero,A;Levy,D
Langmuir
2002,Vol.18(4),  pp.984-986
DOI: 10.1021/la011375g



Abstract
The preparation of sodium salicylate doped sol?gel films and their application as phosphor screens have been studied. The sol?gel process opens the possibility of homogeneously tailoring the overall thickness and chemical composition of such films. The adhesion of the sol?gel processed film to the substrate is noteworthy and, together with the rad-hard characteristics of the silica matrix, contributes to the durability of these films. With regard to the characteristics of the sodium salicylate doped sol?gel films as phosphor screens, the measured relative fluorescence efficiency is found to be among the highest ever reported without adverse affects on the fast response time (4 ns).

A study of a high-pressure thermal argon plasma as a high-radiance standard

1972, Vol.12(7), pp.1089-1104
DOI: 10.1016/0022-4073(72)90012-X




Abstract
This work represents a first step in the realization of a plasma source emitting blackbody radiation. A theoretical evaluation of the conditions to be fulfilled in order to obtain strictly planckian radiation from a pure argon plasma has been made. The plasma generator is a wall-stabilized arc 49 mm in length, burning stably under pressure as high as 50 atm. Spectroscopic diagnostics of the plasma have been performed by using various methods and using the hypothesis that L.T.E. obtains. For a constant value of the electrical intensity (150 A), the electronic temperature decreases from about 14,000°K at atmospheric pressure to about 11,500°K at 50 atm. The continuous radiation has been measured between 1 and 50 atm; the values of the monochromatic brightness temperature were deduced from it and compared with the value of the electronic temperature. For the maximum values of pressure, length, and temperature, the emitted radiation is not Planckian but the brightness temperature TL of the continuum remains constant in a wide spectral range (3500 less-than-or-equals, slant ?[A] less-than-or-equals, slant 6500). In addition, discrepancies also appear between the theoretical forecasts and the experimental values. However, the arc which has been realized can constitute a useful reference source of high radiance in the visible and near u.v. range, because of its time stability and of the reproducibility of the emitted light intensities.

Excitation of the fluorescence of tungstates in the region of the fundamental absorption using synchrotron radiation
Gurvich,A;Meleshkin,B;Mikhailin,V Khundzhua,A
J. App. Spec.
2002, Vol.20(4),  pp.488-490
DOI: 10.1007/BF00941439




Abstract
Fluorescent tungstates of metals of group II of the periodic system, used, in particular, as x-ray luminophors, belong to the class of self-activated crystallophosphors based on salts of oxygen containing acids, which, as a rule, are derivatives of d-transition metals - tungsten, molybdenum, niobium, tantalum, zirconium. It is suggested that the centers of fluorescence are anionic complexes, formed by these elements.

Synthesis, characterisation and photoluminescence of nanocrystalline calcium tungstate

J. Exp. Nano Sci.
2010, Vol.5(3),  pp.263-270
DOI: 10.1080/17458080903513276




Abstract
Calcium tungstate nanocrystalline was successfully synthesised via a microwave irradiation method using Ca(NO3)2 and Na2WO4 in ethylene glycol, without the requirement of any calcination. The product was analysed by X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and photoluminescence spectrometry. XRD, SAED and TEM revealed that the product was body-centred tetragonal CaWO4 with an average particle size of 12 nm. Different oscillation modes were detected by Raman spectroscopy and FTIR. They showed the strong W-O stretching in [WO4]2- tetrahedrons at 711-933 cm-1. Photoluminescence (PL) of CaWO4 nanocrystalline showed the maximum emission peak at 422 nm.


NB These are important if we are going to work out a decent source of UV Radiation, Calcium tungstate fluoresces, emitting a continuum source from 200-500nm when excited with either X-rays or Extreme UV, as Argon Excimer lamps emit over 50nm - ~100-150nm, they may well be sufficient to excite these simple phosphors. If they do that, then a simple dielectric microdischarge, or an array thereof, using fuck all power (high kV/low mA) and two diodes (warm white & blue white) we will have a continuum spectrum all the way to ~800, then we only need to look at the FWHM of the NIR Diodes in order to get the simplest, most cost effective and longest lasting light source possible. It may even be possible to coat the cover of the housing with a couple of phosphors (like the one on white-blue leds), to give us a good visible range as well as the UV-A/B/C, in one tiny package. That will reduce the power consumption of a spectrometer, simplify the shit out of the lighting and make the whole thing seriously cheaper (UV Lights are fucking expensive)

Reliability Aspects of Electronics Packaging Technology using Anisotropic Conductive Adhesives

Liu,Johan;Lu,Xiu-Zhen;Cao,Li-Quiang

J. Shanghai Uni.
Vol.11(1) 2007 pp.1-16
DOI: 10.1007/s11741-007-0101-6

Abstract

Anisotropic conductive adhesive technology for electronics packaging and interconnect application has significantly been developed during the last few years. It is time to make a summary of what has been done in this field. The present paper reviews the technology development, especially from the reliability point of view. It is pointed out that anisotropic conductive adhesives are now widely used in many applications and the reliability data and models have been developed to a large extent for anisotropic conductive adhesives in various applications.

These too are kind of important - I'm basically trying to work out a way to alter the MEM's level approach to get a single round sensor (instead of a suspended grid), which can act as an uncooled microbolometer/microthermopile. Now the thermopile would be best, because it doesn't require a current to put through it - it produces a current, a microbolometer only changes its resistance which means you need a bias current going through it in order to measure the resistance. A microthermopile, an uncooled one at that, would be fucking brilliant - with the little TO-5 Can with partially oxidized tungsten wire running around an alumina core (20-50W), producing the full 1,000nm to 15,000nm spectrum, an equal size TO-5 can sensor would be fucking great.
