Abstract
The invention relates to a laser () with a laser chip () having a plurality of active laser channels (), a front facet () for coupling out the laser radiation of the laser channels () and a rear facet () for rear—side reflection of the laser radiation of the laser channels () in the direction of the front facet (); an external resonator () which couples a portion of the radiation exiting the laser chip () at the front facet () back into the laser chip () and, by said back-coupling, couples the radiation of the laser channels () with one another; wherein at least one of the laser channels () is curved at least sectionally and—in the far field—in addition to a main beam (P), at least one secondary beam (PP) is divergently emitted by the laser chip (); and wherein the resonator () reflects at least one of the secondary beams (PP), which is—in the far field—divergently emitted by the laser chip () next to a main beam (P), in the direction of the laser chip ().
