High-voltage pulse generator based on LTD concept for CuBr+Ne+HBr laser media excitation

Abstract

The paper presents the power supply based on the LTD-generator concept for active elements on metal halide vapors excitation. The main source feature is the modular structure which allow to increase output voltage and change storage capacity due to the number of modules. Each module is designed to minimize parasitic parameters and provide high voltage and current slew rates to the GDT. The limit parameters of one module are as follows: maximum voltage 1100 V, maximum pre-pulse energy in the storage capacity 9.0 mJ. The results of the excitation of the active media at the different pulse repetition frequency are presented. For the first time the 1.5 W radiation power was obtained for the laser excited by this type of power supply.
