摘要： The present invention includes a method for identifying and probing phase transitions in materials. A polymorphic material capable of existing in at least one non-centrosymmetric phase is interrogated with a beam of laser light at a chosen wavelength and frequency. A phase transition is induced in the material while it is interrogated. The intensity of light scattered by the material and having a wavelength equal to one half the wavelength of the interrogating laser light is detected. If the phase transition results in the production of a non-centrosymmetric phase, the intensity of this scattered light increases; if the phase transition results in the disappearance of a non-centrosymmetric phase, the intensity of this scattered light decreases.

摘要： Method for monitoring the crystallization of at least one organic material from a liquid. According to the method, a liquid having at least one organic material capable of existing in at least one non-centrosymmetric phase is prepared. The liquid is interrogated with a laser beam at a chosen wavelength. As at least a portion of the at least one organic material crystallizes from the liquid, the intensity of any light scattered by the crystallized material at a wavelength equal to one-half the chosen wavelength of the interrogating laser beam is monitored. If the intensity of this scattered light, increases, then the crystals that form include at least one non-cetrosymmetric phase.

摘要： A fiber-based optical pressure-sensor, made using semiconductor nanocrystal quantum dots (NQDs) as the active transducing material, provides response time fast enough for shock wave measurements. For NQDs, the shift in band gap as a result of applied pressure can be observed as a shift of the photoluminescence (PL) peak. Further, the shift of the principal absorbance feature allows pressure measurements faster than those obtainable by following the PL peak.

摘要： A device and method for separating oxygen isotopes with an ArF laser which produces coherent radiation at approximately 193 nm. The output of the ArF laser is filtered in natural air and applied to an irradiation cell where it preferentially photodissociates molecules of oxygen gas containing .sup.17 O or .sup.18 O oxygen nuclides. A scavenger such as O.sub.2, CO or ethylene is used to collect the preferentially dissociated oxygen atoms and recycled to produce isotopically enriched molecular oxygen gas. Other embodiments utilize an ArF laser which is narrowly tuned with a prism or diffraction grating to preferentially photodissociate desired isotopes. Similarly, desired mixtures of isotopic gas can be used as a filter to photodissociate enriched preselected isotopes of oxygen.

摘要： A bubble chamber spectrometer provides a new method for the sensitive detection of an analyte in a solvent. A bubble chamber receives a solution containing an analyte to be detected. A laser is adapted to direct an output laser beam through the bubble chamber, where the laser is selected to be absorbed by the analyte and to be transmitted by the solvent. A video camera is adapted to display passage of said laser beam through said bubble chamber so that bubbles in the solvent arising from energy deposition in the analyte can be counted to characterize the analyte both quantitatively and qualitatively.

摘要： Carbon Monoxide vapor is used to generate coherent, tunable vacuum ultraviolet radiation by third-harmonic generation using a single tunable dye laser. The presence of a nearby electronic level resonantly enhances the nonlinear susceptibility of this molecule allowing efficient generation of the vuv light at modest pump laser intensities, thereby reducing the importance of a six-photon multiple-photon ionization process which is also resonantly enhanced by the same electronic level but to higher order. By choosing the pump radiation wavelength to be of shorter wavelength than individual vibronic levels used to extend tunability stepwise from 154.4 to 124.6 nm, and the intensity to be low enough, multiple-photon ionization can be eliminated. Excitation spectra of the third-harmonic emission output exhibit shifts to shorter wavelength and broadening with increasing CO pressure due to phase matching effects. Increasing the carbon monoxide pressure, therefore, allows the substantial filling in of gaps arising from the stepwise tuning thereby providing almost continuous tunability over the quoted range of wavelength emitted.
摘要翻译：一氧化碳蒸气用于通过使用单个可调谐染料激光器的三次谐波产生相干，可调谐的真空紫外线辐射。附近电子水平的存在共振地增强了该分子的非线性磁化率，允许在适度的泵浦激光强度下有效地产生vuv光，从而降低六光子多光子电离过程的重要性，其也被同样地共振地增强电子级别，但更高级。通过将泵浦辐射波长选择为比从单个的振荡电平来的波长更短的波长，从154.4到124.6nm逐步延伸可调性，并且强度足够低，可以消除多光子电离。由于相位匹配效应，三次谐波发射输出的激发光谱表现出转变为较短的波长并随着CO压力的增加而变宽。因此，增加一氧化碳压力允许基本上填充由逐步调谐产生的间隙，从而在引用的波长发射范围上提供几乎连续的可调谐性。

摘要： In XeBr lasers which make use of HBr as the source of bromine, it has been found that the working life of the laser is limited because of dissociation of the HBr in the lasing region to form H.sub.2 and Br.sub.2. Accordingly, apparatus is disclosed for substantially improving the working time of the XeBr laser wherein means are provided for recombining H.sub.2 and Br.sub.2 into HBr and for continuously circulating the gaseous working medium from the lasing region through the recombination region.BACKGROUND OF THE INVENTION
