Abstract

A laser comprises an active element and two resonators wherein each resonator further comprises a highly reflective resonator element and an output coupling element which reflects the radiation of the active element in itself. The active element amplifies incident radiation from a solid angle range by a normal of the active element which is distinctly greater than zero. The resonators are arranged relative to the active element such that each resonator reflects the radiation on the active element at a different angle of incidence within the solid angle range.
