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.     

Photoanisotropic properties of luminescence media for polarization holography based on new-type dyes

The size and shape distributions of particles of a dispersive medium are retrieved from measurements of the scattering matrix for aqueous suspensions of copper and zinc oxides by solving the optimization problem for the sum of the squared deviations of the experimental values of matrix elements and their values calculated using the model of spheroidal scatterers. It is shown that for dispersive media with particles of irregular shapes and with sizes corresponding to the size parameter of 0.1–2, the retrieved distribution has a distortion expressed in an increased fraction of smaller sized particles.

Model description of the degree of polarization of nonstationary light waves

A theoretical approach is developed that provides the possibility of representing partially polarized radiation in the form of a sum of mutually orthogonal polarized and incoherent components and in the form of a model device with a time-dependent circular birefringence. This approach allows one to apply the vectormatrix Jones method in calculations. The possibility of theoretically determining the degree of polarization of the light passed through a corresponding device placed in an external magnetic field is shown as an illustration.
