本文利用光学布洛赫方程的稳态解,讨论连续激光振荡过程。所得到的激光物质的增益和饱和效应、色散和频率牵引的理论公式与兰姆半经典理论中,密度矩阵非对角元的三阶解理论结果完全一致。但这一方法简化了数学过程。

This paper discusses the CW laser oscillation process using the stationary state solutions of the optical Bloeh equations. The derived formulas on gain and saturation effect, dispersion and frequency pulling of the laser material agree with the results obtained by the third order approximation of the non-diagonal element of density matrix in Lamb’s semi-classical theory and this method simplifies the mathematical processes.
