Gas lasers pumped by the generators with inductive energy storage and semiconductor opening switch

Pre-pulse-sustainer circuit technique on the base of the inductive energy storage and semiconductor opening switch generators was developed. It was found that the pre-pulse with high amplitude and short rise-time along with sharp increase of discharge current significantly improve discharge stability and life-time of the volume discharge in halogen containing gas mixtures. The pre-pulse with high pumping power forms high-density discharge plasma and inversion population in gas mixtures under study within ∼10 ns and provides both early one-set of lasing and conditions for efficient excitation of an active medium from the storage capacitor. As a result efficient long-pulse laser action in different gas mixture was obtained.
