The subject of investigation is the formation of a highly efficient multiple-beam diffraction field resulting from acoustooptic diffraction by a periodically modulated acoustic wave and acoustic signal composed of a set of independently generated equidistant frequency components. Conditions for minimization of optical losses associated with higher diffraction orders are analyzed. A highly efficient multiple-beam diffraction field is formed by optimizing the phases and amplitudes of signal independent components. A technique of acoustooptic measurements at a high laser radiation intensity is developed, and the basics of the theory are verified experimentally. An attempt to split the power of a laser beam propagating through an optical fiber into seven channels of equal intensities is realized with a net efficiency of 80%.
