Abstract :
We have studied the possibilities of decreasing the photoinduced lithium niobate acoustic characteristics. We have shown that doping of lithium niobate crystals with Mg impurity and special ultrasonic treatment significantly decreases the sound speed and electromechanical parameter changes in lithium niobate, which were caused by visible light
