A novel two-step optical pumping technique is described for creating line-tunable laser emission in the 2..nu../sub 2/--..nu../sub 2/ band of NH/sub 3/. Two TE CO/sub 2/ lasers operating on the R(30) and P(24) 9-..mu..m transitions are used to pump the sR(5,0) and 2sR(4,3) NH/sub 3/ transitions respectively, and lasing is observed on 11 different NH/sub 3/ lines having wavelengths from 16 to 21 ..mu..m. This pumping technique relies on rapid rotational thermalization in the vibrational levels to enhance the pump absorptions and distribute the population inversion. The possibility of producing cw line-tunable operation on these transitions is discussed.
