Abstract

A high power square wave power supply consisting of fast and high power SCR for pulsed lasers is developed. The pulse width and amplitute can be continuously varied from 0. 5 ms to CW and from more than 10 A to 300 A, respectively. Its current anti-voltage, realiability are better than those of the power supplies consisting of GTR. The operation principle and experimental results are described and the design formula is derived.
