摘要: 根据非线性薛定谔方程,应用分步傅立叶算法,模拟了不同强度的入射超高斯光束在片状放大器中的传输行为。分析了超高斯光束的光束宽度参量、阶数,以及片状放大器中的自由传播空间对光传输的影响。Abstract: The characteristics of a super-Gaussian beam propagating in the amplifier of stacked-slabs have been simulated after resolving the nonlinear Schrdinger equation with the split step Fourier numerical method. The fact which influence the laser propagating in the amplifier of stacked-slabs have been studied, including the waist parameter and order number of super-Gaussian beam and the free space of laser propagation. The light intensities dependent evolutions of a super-Gaussian beam propagating in the amplifier of stacked-slabs have been also analyzed .
