Abstract

We have developed a simple, intuitive semi-analytical ABCD technique that allows transverse gain saturation effects in end-pumped lasers to be accounted for with minimal approximation. The new formalism makes use of an explicit solution to the homogeneous gain-saturation equation and, for most cases, is virtually indistinguishable from a full beam propagation code (BPC).
