acousto-optic device

  • 1Acousto-optic modulator — An acousto optic modulator (AOM), also called a Bragg cell, uses the acousto optic effect to diffract and shift the frequency of light using sound waves (usually at radio frequency). They are used in lasers for Q switching, telecommunications for …
