Random variation of atmosphere refractive index causes changing the optical path. Therefore, it affects the
intensity and phase of wavefront passing through the atmosphere. There are different algorithms for simulating the
propagation of laser beams through turbulent atmosphere. In this article, propagation of high power pulses of laser
with gaussian profile is investigated using numerical simulation and Split-Step method. Phase screens are simulated
using Fourier transform and variations of intensity and phase of laser pulses are investigated. Results of simulations
show that at wavefront phase retrieval process, increasing the number of terms of Zernike polynomials leads to
decreasing the residual phase error.

Keywords: Split-Step algorithm, High power pulses, Atmospheric turbulence, Nd:YAG laser.
