Mode-competition Effects of a Two-mode Laser from Pump Fluctuations with Saturation Effects

研究了泵涨落对双模激光增益模型竞争效应的影响。通过线性稳定性分析得到一些很有意义的结论。

The effect of pump fluctuations on mode competition of a two mode laser with saturation effects is studied. By means of a linear stability analysis, some conclusions have been obtained. In strong coupling, if pump fluctuations are absent, the mode competition effects are such that one mode can build up a stable oscillation and the other is suppressed. However, if pump fluctuations are present, two modes may build up stable oscillations at the same time. In weak coupling, if pump fluctuations are absent, the mode competition effects give rise to two modes which may build up a stable oscillation. However, if pump fluctuations are present, one mode may be suppressed.
