摘要
采用数值仿真的方法研究了增益系数对环形腔激光器输出特性的影响。首先给出了考虑横向效应后环形腔激光器模型的光强方程。进一步通过模拟仿真Lyapunov指数随增益系数的演化确定了激光系统的动力学行为, 并展示了考虑到光场的横向效应后环形腔激光器激光斑图的形成。最后, 通过模拟不同增益系数下的激光斑图来说明增益系数对环形腔激光器输出特性的影响。
Abstract
The influence of gain coefficient on the output characteristics of ring cavity laser is researched by numerical simulation. At first, the light intensity equation of the ring cavity laser model after transverse effect is given. And then, the dynamical behaviors of the laser system are determined by simulating the evolution of the Lyapunov exponent with the gain coefficient, and the formation of laser pattern of ring cavity laser after light transverse effect is demonstrated. At last, the influence of gain coefficient on the output characteristics of ring cavity laser is illustrated by simulating the laser patterns under different gain coefficients.
