A cw CO/sub 2/ laser operating on the R(30) 9-..mu..m transition is down shifted by 180 MHz in a pair of acousto-optic modulators, and used to optically pump sR(5,0) transition of NH/sub 3/ at line center. Vibrational inversion is created in the ..nu../sub 2/ mode, and cw oscillation is observed on 20 different NH/sub 3/ lines, spanning the region between 10.7 and 13.3 ..mu..m. Single line output powers as high as 760 mW were measured in a waveguide cavity. The operation of this laser is explained using a simple thermalization model, and several potential applications are discussed.
