Paper Abstract

Bulk acousto-optic modulation was investigated as a technique for generating high bandwidth linear chirp waveforms for ladar applications. The high modulation bandwidth was achieved by cascading the Bragg cells, in which each cell produces only a fraction of the total bandwidth, and large optical beam diameters and high optical energies can be used. Both germanium and thallium arsenic selenide (TAS) were investigated as acousto-optic materials, and comparisons were made between the two materials. Cooled germanium was also studied as a means of lowering the acoustic attenuation, and the thermal conductivity of cryogenically cooled Ge was measured.
