Abstract

This paper presents a menu-driven computer program developed for numerical simulations of single-mode diode lasers operating well above threshold. The program described here offers additional improvements and increased functionality, allowing us to model a wider class of devices. The software incorporates a subroutine to calculate a set of possible competitor modes using gain and index variations produced by the oscillating mode. These results demonstrated that a single-spatial mode can be maintained to approximately 13.5 times laser threshold. In the absence of thermal effects, it, was found that the experimental data confirms single-spatial mode operation up to at least 12 times threshold, in good agreement with the model.
