Abstract
Evolution of phase singularities is studied when a laser beam propagates through an inhomogeneous turbulent atmosphere. The simulation results reveal that, when the laser beam propagates along an uplink turbulent atmosphere path, the density of phase singularities (DPS) stars at zero and then grows rapidly with the increasing of the propagating height. When the beam propagates to a certain height, the DPS reaches its maximum and then begins to decrease. When the laser beam propagates along a downlink turbulent atmosphere path, the functional form of the DPS has a shape of monotone increasing cure with the decrease of the propagation height and reaches its maximum near the ground.
