Optical device with phase-locked diodelaser array.

摘要

An optical device is described comprising a phase-locked diodelaser array (10), radiating in a stable supermode, and a collimatorlens (46). By arranging a polarisation-rotator (22) and a polarisation-sensitive beam combiner (30') in the radiation path, the two radiation lobes (11, 12) are superposed so that a single radiation spot (S) can be obtained. The quality of the spot can be improved by an arrangement of a prim system (40) and a spatial filter (45) in the lateral far field.
