This paper describes the construction of an optically pumped laser device. The device utilizes a line-tunable CO/sub 2/ TEA laser as a source to optically pump a cell which is capable of cooling candidate laser gases down to approx.150 /sup 0/K. Laser outputs of 750 mJ in the 13-..mu..m region and 100 mJ in the 16-..mu..m region are obtained by pumping NH/sub 3/ and CF/sub 4/ respectively with 10 J of CO/sub 2/ laser radiation. The measured conversion efficiencies are 15% for NH/sub 3/ and 3% for CF/sub 4/. These lasers can be used to photodissociate polyatomic molecules and are attractive sources for practical laser isotope separation.
