Abstract

It has been analyzed the peculiarities of propagation of weakly and strongly divergent Gaussian beams near optical axes of uniaxial and biaxial crystals. It has been determined the dependence of character of the laser beam transformation by scanning near special directions on optical anisotropy of medium. It has been established that in strongly divergent light beams the presence of anisotropy leads to changes of energy distribution in its cross-section. It has been found the correct conditions of propagation of non-aberrational beams in crystals which take into account the influence of anisotropy. It has been investigated display of gyrotropy in polarization, energetic characteristics and beam divergence of optical radiation.
