The formation of two-beam technological laser with use of the high efficiency acoustooptic modulator

A new technique, providing maximal total power and contrast of laser beams, is suggested. The technique is based on amplitude-frequency correction of the controlling signal. Theoretical analysis of the suggested technique is carried out. Experimental investigation of the technique was performed using TeO₂ Bragg-AO modulators. The experimental results are in good agreement with the theoretical ones. The results could be used in a number of industrial applications.
