Abstract
A laser system for the generation of an ultra-short light pulse—with a laser resonator which contains at least one active solid-state oscillator element, preferably a thin disk of a laser-active crystal with a high amplification bandwidth, particularly of a “quasi-three-level” system such as Yb:YAG—comprises at least one respective arrangement for phasecoupling of the laser modes and for dispersion compensation. For industrial applications,in order to be able to emit ultra-short pulses with very high average powers in a power-scalable fashion while being constructed optimally simply and inexpensively, the arrangement for phase coupling is constructed as a passive, non-linear element, and a prismless arrangement for dispersion compensation is provided.
