摘要
采用傅立叶变换法求解谐振腔中的自再现方程,利用二维离散傅立叶变换法对离散点处理比常规迭代法快的特点,计算模拟了高能气体激光器的三维模场,并给出了存在增益介质时模分布图.
Fourier-transform method was used to solve the self-consistent equation of laser resonator.Then the modes of empty high energy gas laser were calculated and given,as well as the loaded laser.Results show that the modes was different in the above two case for the existence of gain medium.
