Abstract

We theoretically investigate suppression of travelling wave instability in the transverse section of broad-area lasers. We investigate influence of the detuning between injected signal and generated radiation. The synchronization conditions were obtained under which the effective suppression of the wave instability occurs. Numerical simulation of the spatiotemporal dynamics of a broad-area laser with injection of external optical signal is carried out.
