Suppression of instability of wide-aperture laser by external optical injection

Abstract

This paper investigates the spatiotemporal dynamics of a broad-area laser with modulation of the pump parameter and external optical injection. It is shown that injection suppresses both the wave instability inherent in semiconductor and solid-state lasers and the Faraday instability arising as a result of modulation of the pump parameter. The parameters of the injection signal are found at which the transverse instabilities are effectively suppressed.
