Patents by Inventor Gabriele M. Hawrylow

Gabriele M. Hawrylow has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • High reflectance laser resonator cavity
    Patent number: 4805181
    Abstract: A ceramic pump cavity structure for use in solid state lasers wherein the pump cavity comprises sintered alumina having grain sizes of between about 0.3 to 0.5 microns. Sintered alumina pump cavities having grain sizes within this range provide desirable diffuse reflectivity comparable to barium sulfate while at the same time providing a structurally strong cavity which is resistant to cracking and breakage. Combinations of the alumina oxide pump cavity with parasitic light absorbers such as samarium oxide are also disclosed.
    Type: Grant
    Filed: March 21, 1988
    Date of Patent: February 14, 1989
    Assignee: Hughes Aircraft Company
    Inventors: James O. Gibson, Victor C. Gearhart, Steven E. Birrell, Gabriele M. Hawrylow
