This paper describes the construction of an optically pumped laser device. The device utilizes a line-tunable CO2 TEA laser as a source to optically pump a cell which is capable of cooling candidate laser gases down to approximately 150 degrees K. Laser outputs of 750 mJ in the 13-microm region and 100 mJ in the 16-microm region are obtained by pumping NH3 and CF4 respectively with 10 J of CO2 laser radiation. The measured conversion efficiencies are 15% for NH3 and 3% for CF4. These lasers can be used to photodissociate polyatomic molecules and are attractive sources for practical laser isotope separation.
本文描述了一种光泵浦激光装置的构造。该装置利用一台线可调谐的二氧化碳横向激励大气压激光器作为光源，对一个能够将候选激光气体冷却至约150开尔文的气室进行光泵浦。通过分别用10焦耳的二氧化碳激光辐射泵浦氨气和四氟化碳，在13微米区域获得了750毫焦的激光输出，在16微米区域获得了100毫焦的激光输出。测得的转换效率对于氨气为15%，对于四氟化碳为3%。这些激光器可用于多原子分子的光解离，是实际激光同位素分离的有吸引力的光源。
