Optical Device for Processing a Beam, in Particular a Laser Beam

摘要

An optical device is used for processing a laser beam. It includes an optical element into which at least one input beam is coupled and out of which an output beam emerges. It is proposed that the optical element include a transparent member which has two mutually opposing surfaces having an intermediate plane, which is oriented in such a way that it subtends a first angle with a first spatial axis disposed orthogonally to the longitudinal axis of the input beam, and a second angle with a second spatial axis disposed orthogonally to the longitudinal axis of the input beam and to the first spatial axis, each of these being greater than zero; an that an incoupling prism for coupling the input beam into the member is provided at the one surface, and an outcoupling prism for coupling the output beam out of the member is provided at the opposite surface of the member; viewed in the direction of the longitudinal axis of the input beam, the incoupling prism and the outcoupling prism covering different regions on the member.
