Pulsed high-power mid-infrared gas lasers

We present a survey in the spectral region of 200-700 cm^-1(14-50 mum) of pulsed mirrorless gas lasers pumped by a TEA CO2laser. 55 lines are found covering the wavelength range 15.8-57 cm^-1in the gases NH3,¹⁵NH3, D2O, CH3OH, CD3OH, and CD3OD. Most of these lines are reported for the first time. One of the strongest lines (26.4 μm in NH3) emits a considerable pulse energy of 100 mJ. No lines were found in C2H5OH and C3H6O.
