Patents by Inventor Dave R. Dudley

Dave R. Dudley 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).

  • Lasers with low doped gain medium
    Patent number: 6504858
    Abstract: A high power, diode pumped laser has a Nd:YVO4 gain media. Scaling to higher powers is achieved with the use of a low doped gain media, increasing the length of the gain media as well as increasing the pump volume. Passive cooling is extended to output powers of 10 W or greater.
    Type: Grant
    Filed: December 20, 2000
    Date of Patent: January 7, 2003
    Assignee: Spectra Physics Lasers, Inc.
    Inventors: Emily Cheng, Dave R Dudley, William L. Nighan, Jr., James D. Kafka, David E. Spence, David S. Bell
