Device for modifying and uniforming the distribution of the intensity of a power laser beam

摘要

A device for modifying and uniforming the distribution of the intensity of a power laser beam is provided wherein a rotatable support body includes three mirrors for reflecting an incident laser beam. The rotation of the mirrors with the support body effects a uniform distribution of the intensity of the incident laser beam resulting in a reflected laser beam having uniform distribution of intensity across its cross section. A modification section is included for modifying the amplitude of the reflected laser beam passing from the support body.
