Abstract

In this paper, spatiotemporal dynamics of broad-area lasers with external optical injection is investigated. We demonstrate theoretically that relatively small optical injection suppresses unstable transverse modes and stabilizes laser output. We perform our study, taking into account the detuning between the frequency of the injected and generated radiation. The frequency detuning does not destroy the stabilizing effect. Parameters of the injected signal, at which effective suppression of transverse instabilities occurs, are found.
