Wide-angular acousto-optical nonpolarized radiation modulator for high-power industrial lasers

Some peculiarities of a process of non-polarized radiation diffraction on ultrasonic waves in uniaxial crystals are examined. Particular calculations are made to single-crystals of paratellurite. The experimental design of an acousto-optical modulator operating with non- polarized multimode laser radiation is reported. Basic parameters of the device are presented as well.
