- Abstract
- The results of developing and construction optimization of copper vapor laser excitation circuit were represented. The main feature of excitation circuit construction is high voltage solid-state switch which consists of a number of series-connected IGBT's. The blocking voltage of the switch is 12 kV and peak pulse current is 100 A. Average output laser power 12 W, repetition rate 15 kHz and total efficiency (light power to electric consumption power ratio) - 0,7 %. In comparison with excitation circuits based on thyratrons and modulator vacuum tubes the present circuit is much more reliable and have much longer lifetime.
