Abstract
An acousto-optical laser modulator includes an X-cut crystal quartz block. A transducer, such as a piezoelectric device, is coupled to the block. An electrical signal provided to the transducer causes the transducer to vibrate. The vibrations propagate through the block as acoustic waves. A laser beam incident on the block may be refracted or diffracted by the acoustic waves. X-cut crystal quartz has various properties such as high thermal conductivity, low acoustic attenuation, high loss modulation efficiency, high drive power efficiency, and low angular sensitivity which make it well suited for applications in acousto-optical devices.
