The small-signal gain of a cw optically pumped 12-..mu..m NH/sub 3/ system is investigated as a funciton of pump intensity, pressure, pump offset, and polarization using a tunable diode laser as a probe. In general, the experiment is found to be in good agreement with calculations based on the theory of two laser fields interacting with a three-level molecular system. Raman gains in excess of 3%/cm are obtained using a waveguide configuration. The significance of these findings is discussed in terms of designing an efficient and powerful cw 12-..mu..m laser.
