Abstract
The performance characteristics and the optimization parameters of a newly developed HF (DF) laser initiated by a novel surface spark UV flash using Teflon are presented. We have obtained an output energy of 0.65 J/pulse (11 J/1, 1.6 µsec FWHM) for HF laser, 0.25 J/pulse (4.2 J/1, 2.0 µsec FWHM) for DF laser with the improved maintenance of the light source. An intense short-pulse surface spark UV source driven by a coaxial Marx generator is realized experimentally in order to improve the power loading, efficiency, and lasing performances at higher operational gas pressure.
