Abstract
An optical system for a laser apparatus includes: a long-short axis reversing module that includes a splitter, a first mirror, and a second mirror positioned in a propagation path of an incident laser beam, where the first mirror includes a first submirror and a second submirror connected to each other at a predetermined angle therebetween. The optical system converts an incident laser beam having an asymmetric energy distribution into an emitted laser beam with a symmetric energy distribution.

An optical system for a laser apparatus comprising:
- a long-short axis reversing module that includes
- a splitter, a first mirror, and a second mirror positioned in a propagation path of an incident laser beam, and
- wherein the first mirror includes a first submirror and a second submirror,
- wherein an edge of the first submirror and an edge of the second submirror are directly attached to each other and a surface of the first submirror and a surface of the second submirror have a predetermined angle therebetween, and
- wherein the optical system converts the incident laser beam having an asymmetric energy distribution into an emitted laser beam with a symmetric energy distribution.
An optical system for a laser apparatus comprising:
- a long-short axis reversing module that includes
- a splitter, a first mirror, and a second mirror positioned in a propagation path of an incident laser beam, and
- wherein the first mirror includes a first submirror and a second submirror,
- wherein an edge of the first submirror and an edge of the second submirror are directly connected and a surface of the first submirror and a surface of the second submirror have a predetermined angle therebetween,
- wherein the long-short axis reversing module mixes a first emitted beam reflected from the splitter and a second emitted beam that passes through the splitter and is reflected from the first mirror and the second mirror to again pass through the splitter into an emitted laser beam, and
- wherein the second emitted beam is inverted in both a long axis direction and a short axis direction with respect to the first emitted beam.
