An acousto-optic modulator (20) includes an acousto-optic bulk medium (42) and a transducer (26) attached to the acousto-optic bulk medium and formed as a linear array of electrodes (28). A transducer driver (22) is connected to each electrode (28) and is coherently phase driven to alter the distribution of an acoustic field and alternately allow and inhibit phase matching between the optical and acoustic field and produce a desired intensity modulation of an optical wavef ront. A plurality of monolitic RF amplifiers (30) supplies power to the array of electrodes (28). |
