Abstract
A solid-state laser has a rod-shaped laser medium with planar end faces and a pumping radiation source whose pumping radiation reaches the laser medium by means of an optical element arranged in a longitudinal configuration adjacent to a planar end face of the laser medium. The optical element is arranged in thermal contact with a cooling element and is optically dimensioned so as to result in a minimum diameter of the transverse mode profile within the laser resonator.
Claims15
A solid-state laser including a laser resonator comprising:
- a rod-shaped laser medium (1) having end faces (1.1, 1.2),
- an optical element (2) arranged adjacent an end face of and in thermal contact with said laser medium (1),
- a pumping radiation source (6) for pumping radiation that reaches said laser medium (1) by means of said optical element (2),
- said optical element (2) being optically dimensioned such that a minimum diameter of a transverse mode profile results within said laser resonator and having at least one optically effective surface that faces said pumping radiation source (6) and is curved to act as an end mirror for a fundamental wavelength of said laser resonator.
