氟化氢泛频20P4,20P5激光谱线大气传输性能实验
Experimental of atmospheric transmittances for 20P4 and 20P5 lines of HF overtone laser
摘要
采用氟化氢泛频化学激光器作光源,在室外实际大气中测量了氟化氢泛频激光20P4、20P5谱线的大气透过率,分析计算了其大气消光系数和大气吸收系数.实验表明氟化氢泛频激光处于大气传输窗口边缘,其谱线的大气传输性能差异很大,证实了20P4是氟化氢泛频选频的首选谱线.
Abstract
In this paper, the atmospheric transmittances, the attenuation coefficient and the absorption coefficient of spectrum lines 20P4 and 20P5 of HF overtone laser are studied. The attenuation coefficient of 20P4 is 0.26~0.27km -1 ,and that of 20P5 is 2.24~2.28km -1 . The absorption coefficient of 20P5 is 20 times bigger than that of 20P4. Simple theoretical analysis indicates that line 20P4 is the optimum line in selecting lines of HF overtone laser.
