Abstract
THE detection1,2 of optical pulsations from the pulsar NP 0532 in the Crab Nebula naturally stimulates a search for optical radiation from other radio pulsars. Of the known pulsars, the southern object PSR 0833–45 has properties most similar to that of the Crab pulsar: the periods of the two objects are the shortest known (33 ms and 89 ms), their principal pulse shapes are very similar, and each seems to be associated with a supernova remnant (the Crab Nebula and Vela X).
