57	Abstract	AB	[DE] Bei einem Verfahren und einer Vorrichtung zum Erzeugen eines koh�renten Lichtb�ndels (10), bei dem bzw. der n > 1 prim�re koh�rente Lichtb�ndel (14) mit zueinander fester Phasenbeziehung jeweils in einen von n optischen Verst�rkern (12) geleitet werden, wonach aus diesen Verst�rkern (12) n sekund�re Lichtb�ndel (16) herausgef�hrt werden, werden die n sekund�ren Lichtb�ndel (16) mit einem ersten optischen System (20) durch phasengerechte Superposition zu dem zu erzeugenden koh�renten Lichtb�ndel vereinigt. [EN] The invention concerns a method and device for generating a coherent light beam (10), wherein n > 1 primary coherent light beams (14) are each passed at mutually fixed phase relations into one of n optical amplifiers (12), whereupon n secondary light beams (16) are guided out of these amplifiers (12). The n secondary light beams (16) are combined with a first optical system (20) by phase-matched superposition to form the coherent light beam to be generated.
