Abstract
We are investigating several classes of versatile, alloptical, open and closed loop circuits that are based on two novel devices: a microchannel spatial light modulator (MSLM) and a laser beamlet array generator (BAG). The MSLM is illustrated in Eig. 1 and is described in detail elsewhere. 1-3 Essentially, it consists of a sandwich of photocathode material, a microchanneJ. plate (MCP), an acceleration grid and a thin electro-optic crystal. The electro-optic crystal is coated on the side lacing the MCP with a dielectric mirror and on the other with a transparent electrode. This entire assembly is enclosed i n of a r e Hz ) and the an evacuated tube.
