Abstract
The operation of various designs of a Faraday isolator with different orientation of a magneto-optical crystal is studied theoretically. It is shown that for different configuration of the isolator, different crystal orientations may be optimal. An original technique was used to measure thermo-optic constants for a terbium gallium garnet crystal which characterize the photoelastic effect. Measurements were made for different orientations of crystallographic axes: (001), (110), (111), as well as for crystals grown by different producers. The results are compared with theoretical estimation. Values of the constants are presented, allowing one to choose such crystal orientation which is optimal from the point of view of isolation at high average power.
