摘要

我最近发现，相位扰动可能会破坏气体激光器的稳态运行，这种稳态运行是由与调谐腔共振的单一驻波模式描述的。这种不稳定性的阈值可能高于或低于由振幅扰动引起的阈值1,2;此外，它与稳态场强和频率的分岔相吻合。行波模式既不发生失稳，也不发生分岔。

Single-mode Laser Instability Induced by Phase Perturbations

I have recently discovered that phase perturbations may destabilize the steady-state operation of gas lasers described by a single, standing- wave mode in resonance with a tuned cavity. The threshold of this instability may lie above or below that arising from amplitude perturbations1,2; furthermore, it coincides with a bifurcation of the steady-state field intensity ℐ and frequency ν. Neither the instability nor the bifurcation is experienced by running-wave modes.
