Abstract
A solid state-gain medium is in the form of a thin disk backed by a reflective coating. A laser resonator is formed by the reflective coating and another mirror. Optical pump radiation is directed into the thin-disk gain-medium for energizing the gain-medium and generating a standing wave of fundamental-wavelength radiation in the resonator. The pump-radiation is directed into the gain-medium at an angle to the resonator axis and pump-radiation fringes are formed by interference between incident and reflected pump-radiation. The pump-radiation angle is selected such that the pump-radiation fringes are aligned with antinodes of the fundamental-wavelength standing wave.
