Paper Abstract

A new design ofthe Faraday rotator is suggested, which can compensate partly for the depolarization that occurs in magneto-optical element because of heating associated with the absorption of laser radiation. The novel design is analytically and numerically compared with the traditional design for both a glass and crystal magneto-optical medium. It is shown that in the novel design the polarization distortions are considerably lower, enabling effective compensation of birefringence in active elements of lasers even when heat release in the Faraday rotator is great. The results obtained in our study indicate that it should be possible to construct a rotator that can provide compensation of birefringence in active elements with an accuracy 1 % at a 1 kW laser power in the rotator.
