We present a set of rate equations for the modal amplitudes and carrier-inversion moments that describe the deterministic multi-mode dynamics of a semiconductor laser due to spatial hole burning. Mutual interactions among the lasing modes, induced by high- frequency modulations of the carrier distribution, are included by carrier-inversion moments for which rate equations are given as well. We derive the Bogatov effect of asymmetric gain suppression in semiconductor lasers and illustrate the potential of the model for a two and three-mode laser by numerical and analytical methods.
我们给出了一组关于模式振幅和载流子反转矩的速率方程，这些方程描述了由于空间烧孔导致的半导体激光器的确定性多模动力学。由载流子分布的高频调制引起的激光模式之间的相互作用，通过载流子反转矩来体现，同时也给出了其速率方程。我们推导了半导体激光器中不对称增益抑制的博加托夫效应，并通过数值和解析方法说明了该模型对于两模和三模激光器的潜力。
