Abstract

We study the gain spectrum of a coherently pumped mid-infrared laser which operates in a linear-cavity (Fabry-Pérot), using a three-level density matrix theory. Arbitrary pump and emission field strengths as well as pressure and Doppler broadening are considered. A new strong directional gain asymmetry is found, which is related to the presence of two counterpropagating components in the standing-wave generated field. Gain lineshapes in a wide range of operating conditions are obtained and analysed. © 1992.
