Random Deflection of Laser Propagating Through Turbulence with Optical Elements
Optical elements may restrain or strengthen the influence of atmospheric turbulence on the properties of laser. Propagation of a laser beam through turbulent atmosphere with optical elements was investigated. Based on the principle of spatial filters, analytical expression for random deflection of a laser beam was deduced. Numerical calculation was given and comparisons with beam wander for the case when there is no optical elements on transmission path were made. It shows that, whether the beam is collimated or not, with the increment in transmission distance, the changing trend of beam deflection and beam wander are roughly the same and that the properties of laser can be improved by using convex lens on its propagation path in turbulent atmosphere.
