摘要: 本文叙述了无镜远红外激光器的结构及其实验结果。用可调谐TEA CO2激光器作为泵浦源,其输出能量在9P(20),9R(22)线上均可达1J左右。用CO29P(20)线泵浦CH3F分子,获得了能量为0.5mJ,波长为496m的激光输出;用9R(22)线泵浦D2O分子,获得了能量为1mJ,波长为385m的激光输出。输出能量和波长是分别用热电堆和Fabry-Perot干涉仪测量的。

Abstract: In this paper, the structure and the experimental results of a mirrorless FIR laser is described. A tunable TEA CO2 laser is used as its pumping source. Its output energy is about 1J at both 9R(22) and 9P(20) lines. Output energy of 0.5 mJ at =496m is obtained with CH3F molecular pumped by CO2 laser 9P(20) line; 1mJ =385m is obtained with D2O pumped by 9R(22) line. A thermopile and a Fanry-Perot interferometer are used to measure output energy and wavelength of FIR laser radiation respectively. -
