Abstract
An optical system includes a diode pump source and a thin disk gain media. The thin disk gain media has first and second surfaces and is made of a material with an anisotropic thermal expansion. At least one of the first and second surfaces is a cooling surface. The thin disk gain media is cut at an angle to provide substantially the same thermal expansion coefficient in all directions lying in a plane that is parallel to the cooling surface. An optical coupler is positioned between the diode pump source and the thin disk gain media to direct an output from the diode pump source to the thin disk gain media.
