ABSTRACT:
An optical beam homogenizer divides and redirects an incident beam to provide uniform irradiation to a plane surface. The beam homogenizer is particularly useful in an apparatus and method for uniform laser irradiation of materials. The apparatus comprises a laser, a beam homogenizer, and a support for the material being irradiated. Depending on the system parameters, the apparatus is useful for metal hardening, semiconductor annealing, or other materials processing applications.
