-
摘要: 本文敘述了無鏡遠紅外激光器的結構及其實驗結果。用可調諧TEA CO2激光器作為泵浦源,其輸出能量在9P(20),9R(22)線上均可達1J左右。用CO29P(20)線泵浦CH3F分子,獲得了能量為0.5mJ,波長為496m的激光輸出;用9R(22)線泵浦D2O分子,獲得了能量為1mJ,波長為385m的激光輸出。輸出能量和波長是分別用熱電堆和Fabry-Perot干涉儀測量的。

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. -
