用增益介质多层分布法模拟非稳腔光束特性
-
摘要: 采用FFT方法和多层增益介质模块处理法研究了非稳腔下具有非均匀流动介质的高功率气体激光器的光束特性和光束质量，该方法比增益介质近腔镜簿层处理法适用性更广。Abstract: Mode calculation in unstable resonators with flowing saturable gain using the fast fourier trans-form(FFT) algorithm and more gain segments method in resonator. This method had more wide-ranging applied .
