AOM = acousto optic modulator. AOM = acousto optic modulator (or deflector)RF signal converted to sound waves in crystalUse fast piezo-electric transducer like Li NbO3Sound waves are collimated to form gratingBragg scatter from grating gives deflected beamcan separate from originalProblem with AOM -- weak linkSound takes time to travel from transducer to laser beamTime delay: tD = l / v -- acts like multi-pole rolloff (phase shift increases with frequency).
