Abstract

A cw CO2 laser operating on the 9R(30) line was used to pump either the sR(5,0) or the sR(5,1) transition of NH3. Collisions with a buffer gas (either N2 or Ar) thermalized the NH3 rotational population, and gain occurred throughout the ν2 band. As there is no collisional coupling of ortho-NH3 (K = 3n) to para (K = 3n ± 1) states, it was necessary to pump the two species separately. Output powers as high as 5.5 W and conversion efficiencies of 33% were measured. A total of sixty-five (ortho and para) transitions were observed to lase at wavelengths ranging from 10.3 to 13.8 μm. The operation of the laser is in good agreement with the predictions of a simple model.
