Comparison Between Two-Level and Inhomogeneously Broadened FIR Three-Level Laser Dynamics

Abstract

The Doppler-broadened FIR three-level laser equations and solutions are analysed and compared to those of a Lorenz-Haken laser. The influence of velocity averaging and optical pumping is found to be large, but it does not give rise to strong new features on the dynamic behavior, which remains similar to that of a Lorenz-Haken laser with effective parameters. Noticeable differences, however, are found between both classes of lasers.
