Optical system for shaping a laser beam and laser system having such an optical system

摘要

An optical system for shaping a laser beam includes an optical element with a base member having a lower base, an upper base, and a lateral surface. The lateral surface includes a transmitting surface for the laser beam, and the base member includes a first cutout portion having a lower base arranged in the upper base of the base member, and a lateral surface that has a first reflecting surface for the laser beam and generates an at least segmentally ring-shaped laser beam. The base member includes a second cutout portion having a lower base arranged in the lower base of the base member, an upper base that includes a transmitting surface for the laser beam, and a lateral surface abutting the lower and upper base. The lateral surface includes a second reflecting surface for the at least segmentally ring-shaped laser beam.

主权项

1. An optical system for shaping a laser beam, comprising:
a first optical element, including:
a base member with a lower base, an upper base, and a lateral surface abutting the lower base and the upper base, wherein the lateral surface includes a transmitting surface for the laser beam;wherein the base member includes a first cutout portion with a lower base arranged in the upper base of the base member and a lateral surface, wherein the lateral surface of the first cutout portion includes a first reflecting surface for the laser beam and wherein an at least segmentally ring-shaped laser beam is generatable by the lateral surface of the first cutout portion;wherein the base member includes a second cutout portion with a lower base arranged in the lower base of the base member, an upper base, wherein the upper base of the second cutout portion includes a transmitting surface for the laser beam, and a lateral surface abutting the lower base and the upper base of the second cutout portion, wherein the lateral surface includes a second reflecting surface for the at least segmentally ring-shaped laser beam; and a second optical element for shaping the at least segmentally ring-shaped laser beam, wherein the second optical element is integrated into the lateral surface of the base member, the lateral surface of the first cutout portion, or the lateral surface of the second cutout portion.
