A high power laser diode array comprising at least one high power diode laser, laser light source comprising the same and method for production thereof

摘要

Disclosed is a high power laser diode array, comprising
at least one high power laser diode (40a-c) comprising a plurality of laser light emitters (2) for emitting output laser beams, each defining, in a direction perpendicular to a direction of propagation (z; z') of an output laser beam, a fast axis (y; y') and a slow axis (x; x');
fast axis collimating means (32) for collimating said output laser beams in fast axis direction (y; y') to provide fast axis collimated output laser beams; and
slow axis beam shaping means (41; 37; 42, 43) for collimating or focussing said output laser beams in slow axis direction (y; y'); wherein
said laser light emitters (2) are displaced relative to each other in fast axis direction and/or slow axis direction by equidistant spacings, respectively; and
an interleaving means (41; 42, 43) is provided for interleaving said output laser beams such that said output laser beams shaped by said fast axis collimating means and said slow axis beam shaping means together form an output laser beam profile (50) in the far field of all laser light emitters consisting of a plurality of fast and slow axis collimated or focussed laser beams (36a-36c; 51) interleaved in a seamless manner in one dimension or in two dimensions with an optical fill factor of 100% or close to 100%.
