| Abstract: | The characteristics of a super-Gaussian beam propagating in the amplif ier 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 dep endent evolutions of a super-Gaussian beam propagating in the amplifier of stacked-slabs have be en also analyzed . |
