Approximate analytical method of gain saturation analysis of hollow waveguide lasers

Not Accessible

Your library or personal account may give you access

Abstract

A simple analytical expression is derived relating the waveguide laser output power to the distributed loss, the mirror reflectances, the waveguide dimensions, and the small-signal gain coefficient. In our model the transverse-mode distributions are taken into account and the longitudinal field distribution is approximated by the threshold field distribution.
