摘　　要：介绍了用于大气吸收测带的电激励双模块小型连续波DF／HF选线化学激光器，描述了其结构、运转方式和激光器的性能。在采刚一级振荡、一级输出的利特罗（Littrow）自准直光栅色散腔结构的前提下，激光器目前共获得17支DF激光谱线，11支HF激光谱线，大部分单谱线基横模输出超过1W，单次连续出光时间超过30min，功率稳定性在±5％以内。将激光器激光光栅改装为球面腔镜后也可输出多谱线DF／HF激光，功率水平为20W，选模后基横模输出6～8W。A discharge driven two-module small scale continuous wave （CW） DF/HF single line chemical laser applied to atmospheric absorption measurement was built. The structure, running manner, and the performance of the laser were described in detail. With the first order oscillating, first order output 1.ittrow grating dispersion laser cavity, 17 DF lines and 11 HF lines are selected. Most of the single lines＇ fundamental mode output exceeds 1 W and stabilizes in 5% scale through the 30 min running time. By altering grating to spherical cavity mirror, 20 W multi line DF lasing and muhi-line HF lasing could be realized with this device, and with an aperture inside the laser cavity to discriminate the higher order transverse modes, 6 ～ 8 W muhi-line fundamental mode lasing could be obtained.
