The objective of this program is the demonstration of a new technique for massless beam steering of high energy laser radiation. Using the effect of nonlinear electrostriction in acousto-optic devices we show large improvements in diffraction efficiency and resolution. These results are obtained through the development of a novel geometry for acousto-optic beam steering and of a prototype device designed to take advantage of this geometry. Theoretical and experimental results of this effort establish the validity of large aperture, high frequency nonlinear acousto-optic beam steering. The results are found to be applicable to steering of high power laser beams. Nonlinear optics, Nonlinear acousto-optics, Beam steering, High power lasers.
