摘要
采用傅里叶变换法求解近轴波动方程,然后利用快速傅里叶变换对二维离散点处理比常规迭代法快的突出特点,模拟了横流CO2激光器输出特性,给出了三维稳态分布图.并探讨了腔镜倾斜、增益非均匀存在时对光腔模式的影响.
Foruier-shaped solution to the wave equation of free space was presented. Then output characteristics for the virtual con.focal unstable resonator of transverse-flow COs laser are simulated using FFT algorithm. The calculation shows effective to solve problem of 3-D discrete sample than commonly used iterative method, especially when the gain and disturbances were concerned.
