摘要
采用平均场近似，用洛仑兹函数来描述增益曲线和自发辐射，得到了多模速率方程组的隐式解析解。在此基础上，着重对阈值附近半导体激光器的载流子密度、输出功率以及阈值电流等重要特性进行了研究。理论和实验结果吻合得很好。
Within the frame of the mean field,using Lorentzian functions to model the gain and spontaneous emission,implicit analytical solutions to the mutli-mode rate equations, including the contributions of spontaneous emission to various diode modes, have been obtained. As a result,with the emphasis on the threshold region,several laser characteristics of importance,such as the carrier density, photon density,etc.have been investigated theoretically and experimentally.
