Abstract
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.
