Modern applications of high frequency acoustooptics

The milestone applications discussion of high frequency acoustooptics is very aim of present paper. The acoustooptical (AO) components such as Bragg modulator (including standing and running wave modulałors), deflectors, others on very high frequencies (up to 10 GHz) working in wide freąuency rangę (up to 3 GHz) are considered, There also discussed some traditional and modern uses of these devices. The main principles and peculiaritieś of Bragg cells design are discussed. The results of experimental investigation are correspond to theoretical predictions. The specific problems, which are stipulated by very high freąuency rangę, are considered. There are: large sound attenuation influence; peculiarities of interaction geometry and light aperture forming; multilayer transducer's features; electrical matching with electromagneticpower wave guide. The ways of High Freąuency Bragg cells parameters optimisation are discussed.
