Abstract

In order to improve upon a laser system, comprising a laser-active medium which is arranged between mutually opposed waveguide surfaces of an optical waveguide and a resonator which by means of resonator mirrors defines a coherent resonator radiation field permeating the optical waveguide and from which a plurality of mutually coherent radiation fields issue, in such manner that higher laser output power levels can be attained it is proposed that the plurality of radiation fields are conducted as coupled-out radiation fields to a coupling element, and that the coupling element combines the plurality of radiation fields with a defined mutual phase relationship to form one single coherent output radiation field.
