Considering the obstruct & transit of the diaphragm for the beam, and using the ray-tracing and split-step Fast Fourier-Bessel transform(SSFFT) methods, we have numerically simulated the evolvement of the beam, which comes from the oscillator of the Q-switched Nd:glass laser with ring cavity and amplified by the Cassegrain multi-pass amplifier.
利用光线追迹法以及分步傅里叶-贝塞尔变换法,考虑了光阑对光束的拦截和通光作用,对环形腔调Q钕玻璃激光系统振荡器输出的光束经卡塞格林式放大器多程放大后的光场进行了数值模拟,给出了基模实心高斯光束演化为环形光束的过程,研究了输入的基模实心高斯光束腰斑半径对输出光场分布和输出能量的影响,并进行了部分实验验证。
