    EMPLOYMENT AND EXPERIENCE HISTORY
    :

    Consultant                                    
    Newport Corporation                               Feb 05 – Jan 14

    In all aspects relating to optical coating technology, including: coating materials, designs, deposition techniques, process control, characterization metrology, manufacturing, etc. for optical components over the spectral range from the deep-ultraviolet (157nm) through the far infrared (15um). Emphasis in high power lasers for industrial cutting / welding and high power laser for computer chip manufacturing.

    NEWPORT CORPORATION
    Principal Scientist                     Jun 00 – Jan 05

    Responsibility: The direction and development of state-of-the-art optical coatings. for application in the microlithography (computer chip systems). This development effort was primarily focused in the deep ultraviolet wavelength region for Argon Fluoride (193nm) and Fluorine (157nm) excimer lasers systems. High reflectance mirrors were successfully manufactured for laser projection application for microlithography chip production. These optical coatings survived, with no degradation in performance, lifetimes exceeding 20 billion 193nm laser pulses.

    STAR OPTICS Inc.                                    Jun 96 – May 00 Founder and President

    Responsible for business administration with the aerospace industry (TRW, Lockheed Martin, and Boeing) and the technical leadership in the production of very low absorption (VLA) optical coatings for high power cw IR chemical laser in application for both spaced-based and ground based Directed Energy Weapons systems. In particular, this technology (light weight uncooled optics) led to the reduction in weight (factor of 10), delivery time (factor of 2) and cost (factor of 7) for the launching of a space based laser satellite missile defense system.


    LASER POWER CORPORATION                     Feb 81 – May 96
    Vice President, Optical Coating Technology

    Responsible for the company’s optical thin film coating technology activities, which were directed through department heads. and brought the ability to produce low absorption, state-of-the-art optics for high-power infrared CO2 laser application. Provided the technical leadership necessary for the design and development of optical components (throughout the ultraviolet-visible-infrared spectral regions). This included: (1) responsibility for technical liaison with the military, aerospace corporations and industrial laser manufacturers for current problems and future needs in the development of optical components and (2) the development of optical coatings for solid state laser frequency doubling systems for laser projection, display and telecommunication applications.

    HUGHES RESEARCH LABORATORIES                Jul 72 – Jan 81
    Head of the Thin Films Section
    Senior Staff Physicist

    Directed basic research and development on the optical properties of thin film coatings for application in the (2 – 15)um IR spectral region. Acted as program manager, principal investigator and technical consultant on numerous government sponsored (DARPA, Navy, Air Force) high energy laser programs. This work included: the design, material processing, fabrication and evaluation / characterization of optical coating structures to provide anti-reflection, high reflectance, beamsplitting, dichoric, etc. performance in optical components for high power IR laser. Coating materials and their designs developed during this tenure are today’s standards for several cw high-energy laser systems, particularly for CO2 industrial laser application.
