Composite Optical Vortices of A Beam in Turbulent Atmosphere
The Evolution law and the types of the wave front edge-dislocation of TEM00 and TEM*01 beams propagating in a weak turbulent atmosphere and in near ground have been discussed by the Rytov approximation. It is shown that the types of the wave front dislocations for light wave propagation in an atmospheric turbulence are dependent on the type of emitting beam and the edge dislocations can be formed by TEM00 beams, the screw dislocations are formed by TEM*01 beams. The dislocation of wave will vanish as the propagation path of wave or turbulent strength increasing due to the decreasing of the contrast of fringes of the beam interference.
