摘要： The invention relates to a laser array that is suitable for injecting laser light into at least one optical fiber. Said laser array comprises a plurality of laser light sources (100-113) which are placed at a distance from a light incidence surface of the at least one optical fiber, and a diaphragm (700) which is suitable for spatially defining the laser light emitted during operation of the laser light sources (100-113) before the same is injected into the at least one optical fiber. The laser light sources (100-113) encompass at least one group of first laser light sources (100-106) and at least one group of second laser light sources (107-113). The inventive laser array further comprises coupling means that are suitable for coupling the laser light together during operation of the first and second laser light sources (100-106, 107-113) before the laser light enters the at least one optical fiber.

摘要： The invention relates to a device for producing laser radiation (4, 16), in particular for laser radiation (4, 16) emitted by a laser diode bar (9), comprising at least one substrate (1, 13, 14, 15) with a plurality of refractive limiting surfaces (2, 3, 17, 18, 19, 20, 21, 22) through which the laser radiation to be produced (4, 16) can pass through in such a way that at least two partial beams (4a, 4b; 16a, 16b) of the laser radiation (4, 16), which, prior to their passage, are adjacently arranged in a first direction (X), are adjacently arranged after their passage through the refractive limiting surfaces (2, 3, 17, 18, 19, 20, 21, 22) in a second direction (Y) which is perpendicular to the first direction (X), the refractive limiting surfaces (2, 3, 17, 18, 19, 20, 21, 22) being formed at a substrate (1) or at substrates (13, 14, 15) which are connected to one another.
