Abstract

Method and laser oscillator for the generation of a laser beam—According to the invention with a view to adjusting, inside said laser oscillator (1), the phase of each of the N elementary laser beams (FLE.1, FLE.2, FLE.N) generated on the basis of said laser oscillator (1) in such a way that said elementary laser beams are in phase, the deviation between the phase of an individual elementary laser beam (FLE.1) and the phases of the N−1 other elementary laser beams (FLE.2, FLE.N) is converted into a level of luminous intensity by means of at least one optical filtering element to which at least a part of each elementary laser beam is directed.
