Abstract
An acousto-optic deflector is supplied with a beam of laser light and driven in a parallel relationship with a plurality of high frequency signals to produce a plurality of diffracted deflected beams of laser light. The high frequency signals have phases independently controlled so as to prevent the resultant combination of the high frequency signals from having an excessively high peak-to-peak amplitude.
