Abstract

Operating conditions for a tunable XeCl excimer laser have been optimized for tunable narrow-band operation at 222 nm with KrCl, formed in Kr/He/Ne/HCl gas mixtures. This wavelength is interesting for detection of nitric oxide (NO) in combustion environments. The laser emission coincides with the (1, 1) and (2, 2) bands of the NO A-X system. Laser-induced-fluorescence spectra taken in a flame show specific excitation of NO with this laser.

摘要

已对可调谐XeCl准分子激光器的运行条件进行了优化，以实现其在222 nm处的可调谐窄带运行，该波长下通过在Kr/He/Ne/HCl气体混合物中形成KrCl来实现。此波长对于在燃烧环境中检测一氧化氮（NO）具有重要意义。激光发射与NO A-X系统的（1,1）和（2,2）波段重合。在火焰中采集的激光诱导荧光光谱显示，该激光对NO具有特定的激发作用。
