Abstract

Concurrent passive mode-locked and self-Q-switched operation of laser devices is modeled using the complex cubic-quintic Ginzburg-Landau equation. Experimental observations use a passively mode-locked fiber ring laser with a waveguide array as a fast saturable absorber. The shape of each individual self-Q-switched pulse and the periodic trains of pairs of such pulses are in a good qualitative agreement with the numerical results.

摘要

利用复立方-五次金兹堡-朗道方程对激光器件的同步被动锁模和自调Q运转进行了建模。实验观测采用了一个以波导阵列作为快速饱和吸收体的被动锁模光纤环形激光器。各个自调Q脉冲的形状以及此类脉冲对的周期序列与数值结果在定性上吻合良好。
