DEVICE FOR THE BEAM SHAPING OF AN INCIDENT LASER BEAM
A device for beam shaping of a laser beam includes a prism, a polarization rotator, and a thin-film polarizer. The prism is configured to split an incident laser beam into a first beam half and a second beam half. The first beam half is input coupled into the prism. The first beam half enters the pr...

| description | A device for beam shaping of a laser beam includes a prism, a polarization rotator, and a thin-film polarizer. The prism is configured to split an incident laser beam into a first beam half and a second beam half. The first beam half is input coupled into the prism. The first beam half enters the prism at a first incidence side arranged at the Brewster angle vis-à-vis the incident laser beam. The first beam half input coupled into the prism is output coupled from the prism at an exit side of the prism at the Brewster angle. The thin-film polarizer is traversed by the first beam half output coupled from the prism. The polarization rotator rotates a polarization of the second beam half. The second beam half is reflected by the thin-film polarizer. The thin-film polarizer superimposes the first beam half and the second beam half. |
