Mechanism of single longitudinal mode operation of semiconductor diode laser with an external cavity

本文建立了一种外腔半导体激光器单纵模机制的模相互作用模型。由于引入四波混频耦合项,模相互作用的效应对次级模的影响是对称的,均使次级模受到增益抑制。

This paper, presents the mechanism of the mode interaction for single longitudinal mode operation of a diode laser with an external cavity, based on the rate equation approach. Due to the coupling term of the four-wave mixing, the mode interaction has a symmetric effect on the submodes, inducing the gain suppression on them.
