Abstract

A PLZT wafer modulates a laser light beam while dissipating heat into a heat sink. The rear side of the wafer is coated to act as a mirror to reflect incoming light and to transfer heat from the wafer. The front side of the wafer has electrodes, separated by a gap through which a laser light beam can pass. An incoming light beam is modulated by the PLZT when it is energized by an electric field on the two front side electrodes. The mirrored side reflects the beam so that it exits the front side.
