Abstract: A method and apparatus are provided for generating light such as ultraviolet light from excimer-forming gases. Gases are excited by radio frequency alternating current powered electrodes (200, 210) to form excimers that will decay and emit vacuum ultraviolet light. The halogen concentration is optimized so as to optimize emissions from halogen excimers (Z 2 *) or mixed rare gas/halogen excimers (RGZ*). Emissions from rare gas excimers (RG 2 *) are maximized by maintaining the gas in the discharge region at a relatively low temperature, desirably below 700 °K, so that the average kinetic energy of gas particles is less than the vibrational excitation energy of the excimer and substantially less than the dissociation energy of the excimer. Relatively large electrodes (202, 204) can be used to cool the plasma.

Abstract: Excimers are formed in a gas (30, 130) by applying a pulsed potential between a first electrode (14, 114) and a counter electrode (26, 126) so that corona discharge occurs, substantially without arcing, when the potential is on. The pulses or on-times of the potential desirably are about 100 microseconds or less. Use of a pulsed potential provides greater efficiency than a constant potential. Where the excimer-forming gas is a pure inert gas, the gas desirably contains less than 10 ppm water vapor.

Abstract: Analytical apparatus and methods for processing multiple samples simultaneously. Radiation such as laser light desirably including plural wavelengths (12, 14) is directed through multiple samples (32 a-d) simultaneously, as by directing a beam of radiation along a single path through all the samples. Response to each wavelength is monitored by monitoring an induced effect, other than the intensity of the applied radiation itself (42). Useful signal to noise ratios are obtained with low absorbance in each sample. One sample desirably is of known composition, and serves as an internal calibration standard.

Abstract: A surface of a ceramic article, such as a glazed surface on a whiteware article, is treated with radiant energy such as infrared light from a laser to provide a localized remelting of the material at the surface in a fusing step. After the fusing step, the surface is treated with further radiant energy, desirably over a larger surface encompassing the fused zone and also desirably at a lower power density so as to limit the rate of cooling of the fusion zone and the immediately surrounding regions, thereby preventing thermal stress cracking. The fusion zone and surrounding regions desirably are preheated by additional radiant energy immediately prior to the fusing step so as to further limit thermal stresses during the fusing step. The process can be employed, among many other uses, for repair of glaze defects and for decoration.

Abstract: The isotopic composition of a multiatomic isotope-bearing species such as CO2 in an analyte is measured by maintaining the analyte in a condition such that isotope-bearing species are present in an excited state and directing light at wavelengths corresponding to transition energies of isotope-bearing species with different isotopes. The interaction between the analyte and light at the different wavelengths is monitored, as by monitoring the optogalvanic effect caused by the light of the different wavelengths. The light may be supplied by a laser (10) including the isotope-bearing species. A stable isotope such as C or O can be used as a tracer in a chemical or biological test and detected using the composition-determining method.
