Laser assembly

摘要

The arrangement has a folding element (7) by which two resonator branches (1a, 1b) are connected, where the folding element is highly reflective for fundamental wavelength. The resonator branches are arranged in V-shape, where active volumes are assigned to the respective resonator branches and are pumped at one side using a common lens (11) of a pumping imaging system (25) by the folding element. The folding element is transparent for pumping wavelength and is formed as a highly reflective surface of an outer side of the lens.
