  • Non-confocal unstable laser resonator and outcoupler
    Patent number: 5943358
    Abstract: An unstable laser resonator geometry with a gradient reflectivity mirror M) and external lens, or a gradient reflectivity mirror-lens (GRML), achieving a vast improvement in the intrinsic divergence and brightness of the output laser beam.
    Type: Grant

  • Relativity stereo scan
    Patent number: 5526039
    Abstract: An observation technique for observing relativistic phenomena by time-like eparated viewing, so as to achieve the enhanced perception as a relativistic phenomena, and its simulation technique. The observation technique includes placing two or more observation devices at time-like separated positions, obtaining data from each device, and viewing the data in stereo such that there is displayed the relativistic phenomena by time-like separated viewing. The simulation technique includes viewing a non-relativistic phenomena with at least one viewing device, obtaining a data vector stream at a set rate, dividing each data vector into slices, and generating two separate data vector streams for stereo viewing utilizing sequential slices of each data vector steam such that there is displayed a simulation of relativistic phenomena for time-like separated viewing.
