单模一类均匀加宽激光器的不稳定分析

The Single Model Analysis in The Homogeneously Broadened Laser Instability

本文采用驻波腔激光器的麦克斯韦—布劳赫方程,对均匀加宽激光器在γ>>x>>γ_(11)和单模近似下进行了线性稳定性分析,得到了二次特征方程λ~2+α_1λ+α_2=0,分析结果表明:参数x,δ_(AC)和σ对Reλ都有影响;当x和σ取定时,δ_(AC)越大,Reλ则越小;σ取适当值时,入具有最大值。

It has been stated that the Maxwell-Bloch equations describe theFabry-Perot cavity laser. In the case of r_1≥κ≥γ_(11) and Single model, bymaking the linear stability analysis, the characteristic equation λ~2+a)1λ+a_2 = 0is obtained in this paper.The results show that the parameters κ,δ_(AC) and σhave effects on Reλ. The bigger δ_(AC), the smaller Reλ. when σ takes thesuitable value, Reλ has the biggest value.
