Polarization-holographic reversal of the front of a reconstructed wave

The formation of an image by a wave conjugate to the reference wave is considered theoretically. It is shown that the polarization hologram formed upon summation of two beams with mutually orthogonal circular polarizations does not yield conjugate or ghost images in the course of reconstruction. The application of the photoinduced anisotropy in polarization-sensitive dynamic media for the correction of laser radiation with a complex polarization distribution over the wavefront is proposed and tested experimentally. The installation of polarization-holographic correctors both outside the cavity and in the intracavity volume of the laser provides the possibility of achieving divergences close to the diffraction limit at a high energy output.
