N2O laser pumped by an SSVD

Abstract

An investigation was carried out into the parameters of an N2O laser pumped by an SSVD with the aim of improving the output characteristics of this laser. The discharge was ignited as a result of a preliminary filling of the discharge gap with electrons and preionization of the gas in the gap by a low-current beam of accelerated electrons. In this way, it was possible to reach an output energy up to 465 J, a specific output energy up to 16.4 J L atm and an efficiency of 6.7%, all of which exceeded the earlier values reported for N20 lasers pumped by an SSVD.
