Paper Abstract

Recent advances in compact, air-cooled, diode-pumped solid- state visible microlasers have enabled the development of portable laser display systems. In addition to the added benefits of large color gamut, invariant color accuracy, image uniformity, high contrast, and large depth of focus inherent in the microlaser design, the reliability of these all-solid state red-green-blue (RGB) sources make them attractive for display applications. Compact, multi-watt laser modules have been demonstrated for use as a high brightness 'laser light engine' for replacing arc lamps in LCD/DMD type display configurations. Using this 'backlit' approach, a microlaser- based projector has been demonstrated, providing greater than 500 lumens at 1280 X 1024 resolution using reflective AMLCD light valves. Also being developed is an airborne tactical HMD system wherein the laser module is remotely coupled to a subtractive color LCD assembly through an optical fiber to provide a more than 24,000,000 (twenty-four million) cd/m2 luminance for illuminating the LCD assembly. This technology could be applied to a variety of cockpit displays providing sunlight readable illumination for both head-down and head-up backlit display configurations. The advantages of the microlaser technology will enable further applications in other military platforms such as command and control centers, simulators and HMDs. Longer term potential includes high end CAD workstations, entertainment systems, and electronic cinema.
