The design and operation of acousto-optic (AU) Bragg cells at center frequencies in excess of 3 GHz are considered. The high frequencies involved severely limit the choice of AO material and mode due to acoustic attenuation. In addition, transducer design becomes increasingly difficult. Experimental results for Bragg cells operating at center frequencies up to 7 GHz are presented.
