Michael L. Marable 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).

  • Optical method and system for analyzing or inspecting patterned materials
    Patent number: 7495823
    Abstract: A method to determine at least one characteristic of a material having a spatially modulated nonlinear susceptibility includes measuring scattered light in response to an incident beam provided to at least one surface of the material. An indication of patterning of the material is determined based on the measured scattered light.
    Type: Grant
    Filed: August 25, 2006
    Date of Patent: February 24, 2009
    Assignee: Northrop Grumman Corporation

  • Optical parametric oscillator with monolithic dual PPLN elements with intrinsic mirrors
    Patent number: 6167067
    Abstract: The present invention relates generally to an apparatus that increases the conversion efficiency of optical parametric oscillators and also reduces overall system size and susceptibility to vibration. The first embodiment of the present invention incorporates a PPLN OPO architecture which includes mirrored coatings on the entry surface area and exit surface area of a monolithic nonlinear optical medium. The coatings act as mirrors, however, the mirrors are actually affixed to the PPLN element. In the first embodiment of the present invention, the PPLN element is a dual grated element. The second embodiment of the present invention uses a single grated PPLN element.
