Delay-differential-equation modeling of mode-locked vertical-external-cavity surface-emitting lasers in different cavity configurations

Abstract

A simple, versatile model for the dynamics of electrically and optically pumped verticalexternal- cavity surface-emitting lasers, which are mode locked by a semiconductor saturable-absorber mirror, is presented. The difference between the laser operation in the linear and folded cavity, as well as the potential for a colliding pulse operation, are studied.
