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.

Expansion matched thin disk laser and method for cooling

An optical system has a high power diode pump source and a thin disk gain media. An optical coupler is positioned between the diode pump source and the thin disk gain media. The optical coupler produces a beam with a large numerical aperture incident on the thin disk gain media.

Thin disk laser with large numerical aperture pumping

An optical system has a diode pump source, and a gain media made of a material with an anisotropic absorption. The gain media is cut at an angle to produce substantially polarization-independent absorption of a pump beam. An optical coupler is positioned between the diode pump source and the gain media. The optical coupler produces a pump beam that has substantially equal amounts of pump power along any two orthogonal axis that are orthogonal to the pump beam in the gain medium. The wavelength range allowed for the pump source is extended.
