The operation of various designs of a Faraday isolator at high average power with an arbitrary orientation of a cubic magneto-optical crystal is studied theoretically. It is shown that in different Faraday isolator designs, different crystal orientations may be optimal from the standpoint of isolation. Thermo-optic and photoelastic constants for terbium gallium garnet crystals grown by different producers were measured. Measurements of self-induced depolarization were made for various orientations of crystallographic axes. The measurements are in good agreement with theoretical predictions. Based on the obtained results it is possible to choose such crystal orientation for Faraday isolators which is optimal from the standpoint of isolation at high average powers.
