Abstract:
Two methods for the dynamic correction of laser wave fronts are considered. The first method is based on a redistribution of the energy between two coherent beams interacting with an induced (by the beams themselves) three-dimensional phase hologram. An efficient redistribution occurs if the phase grating is shifted by one quarter of its period relative to the interference pattern. In the second method a dynamic holographic method is used to form a wave of such a shape that it becomes plane after passing through a laser amplifier. The possibility of experimental realization of the proposed methods is considered.
