ABSTRACT:
A pulse generator comprises a toroid (11) of a superconducting material such as Niobium on a glass or ceramic substrate (12). A cryogenic source such as liquid helium cools the toroid to within a few degrees of absolute zero and a perpetually circulatory current is set up in the toroid. A laser beam is fired at the toroid to cause localized heating and the resultant current drop due to the material resistance causes an output pulse to be induced in an adjacent current winding (14).
