ABSTRACT:
A optical logic device is described in which binary logic functions are accomplished by use of a laser, such as a dye laser, whose output has a polarization direction which is determinable by the direction of polarization of an input excitation laser pumping pulse. An optical component, such as a birefringent element, establishes a pair of bistable polarization directions representative of the binary logic levels. Bistable polarization operation is achieved by requiring a greater intensity of an input laser pumping signal to establish one polarization direction when compared with the input intensity required to establish the other polarization direction. A Brewster plate may be employed to establish the bistable operation of the laser medium.
