Abstract
An optically pumped semiconductor disk laser including a pump light source, at least one semiconductor body (), which semiconductor body () has at least one window region (), an active region () and a reflection device (P), which reflection device has at least one first P-reflection element (P) for the pump wavelength. The first P-reflection element (P) is embodied and arranged such that pump light emerging from the pump light source () can be guided for at least two passes through the active region (). A total thickness of the active region () and of the window region () in the direction of an optical axis of the semiconductor disk laser is less than three times the laser wavelength in the active region ().
