Optics for Beam Shaping in Laser Processing
- 312 Downloads
The shaping of the intensity and/or phase distribution of a laser beam during the laser irradiation of materials is of critical importance for enhancing efficiency, precision, and functionality in laser manufacturing. In this chapter, optics for laser beam shaping in laser processing is introduced. Specifically, beam homogenizers, optics for generating nonconventional beams, multi-focus optics, and mask projection optics, which are the most widely used optics for laser materials processing, are described.
