Abstract

The invention relates to a solid laser system with a longitudinal excitation configuration, as well as to a method for operating it. The solid laser has the following features: a laser medium (1), which is arrangement inside a laser resonator (5) and formed from a laser-active solid material, and excitation source (2) with a laser diode arrangement that is configured for generating pulsed excitation beams, and; a fiber launching device, which is configured for launching pulsed excitation beams from the excitation source (2) along the optical axis of the laser resonator (5) into the laser medium (1). The laser diode arrangement is configured in such a manner that the pulsed excitation beams are supplied with a pulse peak power of at least 400 W.
