A High-Frequency Discharge Module with Power Feedback for the Pumping Systems of Solid-State Lasers

摘要

A discharge module allowing the formation of arbitrarily shaped power pulses with durations of up to 1 s and pulse energies of several kilojoules in the pumping lamp has been developed. Transient processes in the circuit are analyzed and the main parameters of the converter at a given pulse energy are determined. Features of the high-frequency converter's operation with power feedback into a nonlinear load under the conditions of a severalfold decrease in the storage voltage are considered. A circuit for controlling the power-regulating switch and maintaining the relative value of power pulsations in the lamp at a constant level is proposed.
