Abstract: When the high energy laser propagates through the atmosphere, many atmospheric turbulence effects appear, including the beam drift, beam jitter, beam expansion and so on. Based on the wave optical theory, a four-dimensional computer code simulating the turbulence effect was established in this work. The influence of turbulence on different waveform laser, such as the Gaussian laser and the rectangle laser, was calculated. The numerical results show that when the turbulence becomes stronger, the phase aberration of laser become larger and the power in the bucket and the focusing ability become weaken. A comparison between the Gaussian beam and rectangle beam indicates that the turbulence effect on the latter is weaker under the same other conditions and it may be a better candidate to reduce the turbulence effect.
