Abstract :
The gain of a 12-μm NH3 laser transition, optically pumped by CO2 laser radiation, has been measured under well-characterized conditions. Good agreement is found between the measured gain and theoretical calculations based on a three-level density matrix formalism. The theory was also employed to explain the stable frequency behavior of the NH3 laser
