摘要：
The necessary conditions for high-effective multi-beam Bragg acoustooptic diffraction (i.e. laser beam splitting into several beams of predetermined powers) are found. The effect is observed in case of the input electric signal being a combination of several monochromatic components with equidistant frequencies and predetermined amplitudes and mutual phases. An optimizing algorithm for diffraction efficiency maximization is developed. The high-effective splitting into 3-7 beams is experimentally realized.
