Paper Abstract

There are presented results of theoretical investigation of self- depolarization effect in transparent isotropic materials resulting in variation of initial space distribution of polarization-ellipse parameters of focused high-power laser beam. Qualitative results are obtained within non-paraxial approximation while detailed calculations are done within paraxial approximation. In particular, both linear and circular initial polarizations are shown to change and turn into elliptic polarization with inhomogeneous distribution of polarization ellipses in focal area. Detailed calculations are presented for particular case of low-order Gaussian beams (TE00, TE01, TE10 and TE11). Bearing in mind obtained results, we discuss specific symmetry structures of self- depolarization effect allowing experimental checking of described phenomenon.
