Measurements of Thermo-Optical Characteristics of Cubic Crystals Using Samples of Arbitrary Orientation

A method for measuring thermo-optical characteristics of cubic crystals having arbitrary known orientation has been developed. Unlike the traditional techniques, it does not demand samples of specified orientation that greatly expands the scope of its applications and frequently makes it indispensable when novel optical media should be investigated. Experimental verification of the technique using a well-studied TGG crystal shows a convincing agreement between the results obtained by the new and the conventional methods.
