Abstract
Large-aperture Faraday isolators with compensation of thermally induced polarization and phase distortions of highpower laser radiation have been studied experimentally. The degree of isolation is considerably increased up to 24-26 dB at 10-750 W power for one Faraday isolator and up to 42 dB at 10-200 W power for another Faraday isolator and is limited by the quality of TGG crystals. Phase distortions are also considerably reduced.
