  • POLARIZATION MANIPULATION OF FREE-SPACE ELECTROMAGNETIC RADIATION FIELDS
    Publication number: 20210239893
    Abstract: Technology is provided to transform spatially variable arbitrary polarization states and wavefront of a high-fluence, large-aperture laser beam to prescribed spatially resolved polarization states and wavefront at a specific position, with minimal losses. Technology is also provided to transform spatially resolved polarization states and wavefront at a specific position to spatially variable arbitrary polarization states and wavefront.
    Type: Application

  • Combined advanced finishing and UV laser conditioning process for producing damage resistant optics
    Patent number: 6920765
    Abstract: A method for reducing the density of sites on the surface of fused silica optics that are prone to the initiation of laser-induced damage, resulting in optics which have far fewer catastrophic defects, and are better capable of resisting optical deterioration upon exposure to a high-power laser beam.
    Type: Grant
    Filed: April 17, 2002
    Date of Patent: July 26, 2005
    Assignee: The Regents of the University of California
    Inventors: Joseph A. Menapace, John E. Peterson, Bernardino M. Penetrante, Philip E. Miller, Thomas G. Parham, Michael A. Nichols
