摘要 | The invention relates to a laser (1) with a laser chip (10) having a plurality of active laser channels (20), a front facet (10a) for coupling out the laser radiation of the laser channels (20) and a rear facet (10b) for rear—side reflection of the laser radiation of the laser channels (20) in the direction of the front facet (10a); an external resonator (50) which couples a portion of the radiation exiting the laser chip (10) at the front facet (10a) back into the laser chip (10) and, by said back-coupling, couples the radiation of the laser channels (20) with one another; wherein at least one of the laser channels (20) is curved at least sectionally and—in the far field—in addition to a main beam (P3), at least one secondary beam (P1, P2) is divergently emitted by the laser chip (10); and wherein the resonator (50) reflects at least one of the secondary beams (P1, P2), which is—in the far field—divergently emitted by the laser chip (10) next to a main beam (P3), in the direction of the laser chip (10).; The invention relates to a laser (1) with a laser chip (10) having a plurality of active laser channels (20), a front facet (10a) for coupling out the laser radiation of the laser channels (20) and a rear facet (10b) for rear—side reflection of the laser radiation of the laser channels (20) in the direction of the front facet (10a); an external resonator (50) which couples a portion of the radiation exiting the laser chip (10) at the front facet (10a) back into the laser chip (10) and, by said back-coupling, couples the radiation of the laser channels (20) with one another; wherein at least one of the laser channels (20) is curved at least sectionally and—in the far field—in addition to a main beam (P3), at least one secondary beam (P1, P2) is divergently emitted by the laser chip (10); and wherein the resonator (50) reflects at least one of the secondary beams (P1, P2), which is—in the far field—divergently emitted by the laser chip (10) next to a main beam (P3), in the direction of the laser chip (10). |
