Feedback control for a high-frequency generator having a pulse-repetition frequency mode, particularly for exciting a laser

U.S. Patent Number: 5384800

Abstract: The present invention relates to the feedback control of the power output from a high-frequency generator for supplying a pulsed laser. During a pulsing operation, the power output is regulated by means of a controllable grid-leak resistor in the grid circuit of the valve tube of the high-frequency generator. An equivalent system is preselected for the feedback control in the pulse intervals and, consequently, transient reactions are minimized.
