Abstract

The beam spot will break up into some cracks when laser propagates through the turbulent atmosphere. The characteristics of the cracked beam spot are studied statistically for different apertures and beam qualities, and with different turbulent strengths. It is shown that, with the degeneration of the beam quality and the turbulence being stronger, the total size of the beam spots and the numbers of the fragments will increase; meanwhile the scale of the fragments will keep invariable almost. Four special situations are analyzed and the physical hypostasis of Fourier transformation is discussed to understand these results.
