Paper Abstract

Stripe domain garnet light deflectors are being developed to have the increased deflection efficiency needed to perform the optical beam steering function in a laser crosslink, intersatellite communication system. Two approaches are being taken to develop a deflector with a goal of greater then 50% efficiency at 0.8 and 1.06 μm wavelengths. These are development of garnet materials with increased magneto-optic performance and operation of the garnet element in a Fabry-Perot etalon. Modeling of etalon behavior and anticipated garnet material properties indicates efficiencies up to 90% are possible at 1.06 μm and up to 60% at 0.8 μm. At our present stage of material development and without an etalon, efficiencies of 11% at 0.8 μm wavelength and 14% at 1.06 μm have been achieved.
