Patents by Inventor W. Terry Rawlins

W. Terry Rawlins 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).

  • Optically pumped micro-plasma
    Patent number: 9647414
    Abstract: A laser and methods for providing a continuous wave output beam. The laser and method includes positioning a micro-plasma chip capable of creating micro-plasmas within a resonant cavity. A gas is input into the resonant cavity and flows around the micro-plasma chip. Micro-plasmas ignite and excite the gas to create metastables. The metastables are further excited by an optical pump having an energy sufficient to cause the metastables to lase.
    Type: Grant
    Filed: January 30, 2014
    Date of Patent: May 9, 2017
    Assignee: Physical Sciences, Inc.

  • Catalytic generation of metastable singlet oxygen
    Patent number: 9036676
    Abstract: Singlet oxygen metastables can be formed. A catalytic coating is formed on an interior surface of a flow reactor, and an oxygen containing species is flowed into the flow reactor to produce singlet oxygen metastables by a chemical reaction in the presence of the catalytic coating.

  • High-power, high-throughput microwave discharge singlet oxygen generator for advanced electrical oxygen-iodine lasers
    Patent number: 8432949
    Abstract: A laser device includes an optical resonator, a microwave driven discharge device, and a source for a second gas. The microwave driven discharge device is disposed relative to the optical resonator. The microwave driven discharge device operates at a discharge power and gas flow rate to produce a selected amount of energetic singlet oxygen metastables flowing in the direction of the optical resonator. The second source for the second gas is disposed between the optical resonator and the microwave driven discharge device. The second gas reacts with the selected amount of energetic singlet oxygen metastables to form an excited species in an amount sufficient to support lasing of the excited species in the optical resonator.
