Using a continously tunable pulsed 20-atmosphere CO2 laser as a pump source, we generated pulses of mid-infrared radiation, partly tunable in frequency intervals in the range between 200 and 900 cm(-1) via stimulated Raman scattering in gaseous ammonia. As a Raman cell we used a multiple pass cell. We observed for (NH3)-N-14 and (NH3)-N-15 laser lines at 52 different frequencies with 39 lines observed for the first time. Tuning ranges up to 150 GHz and peak powers of several MW were achieved. The quantum efficiency reached 40 %.
