被动锁模固体激光器中可饱和吸收体的弛豫时间对锁模脉冲的影响

Effects of the Relaxation Time of Saturable Absorbers on the Mode-Locked. Pulses In Passively Mode-Locked Solid-State Lasers

本文对被动锁模固体激光器提出一个把涨落模型和准稳态解析方法结合起来的理论模型。用这个模型可以通过计算机模拟算出可饱和吸收体的弛豫时间对输出脉冲的影响,清楚地揭示出脉冲在激光器腔内演变的物理过程。

In this paper a theoretical model for passively mode-locked solid-state lasers is presented, which combines the fluctuation model with the quasi-steady-state analysis. The effects of the relaxation time of saturable absorbers on the output pulses can be calculated by computer simulation with this model. The physical processes of the svolution of a laser pulse in a laser cavity are clearly shown.
