Abstract
An acousto-optic modulator having an ultrasonic medium for controlling light from a light source by diffracting the light and a transducer portion having electrodes for generating an acoustic wave in the ultrasonic medium, wherein the transducer portion includes two transducers each having an electrode. The AOM is provided with two electrodes by using two transducers, thereby facilitating impedance matching with a driver. The two transducers may be installed so that their polarization directions are opposite to each other, thereby obtaining maximum power transfer to the ultrasonic medium.
