Investigation of the characteristics of a magnetically tunable pulse spin-flip laser

A magnetically tunable laser, emitting in the range 9.6–12.2 м, was constructed. It was pumped with various СO₂ laser lines hi the range 10.2–10.9 м. Stimulated emission from this laser was obtained at the Stokes and anti-Stokes frequencies. A system composed of a gate amplifier and a signal store was used to record the absorption spectrum of ammonia in the 11 м range. The measured width of the stimulated emission line, which governed the resolution of the laser spectrometer, was 0.2 cm^–1. Factors responsible for the broadening of this line were considered.
