Influence of the pump power and of the addition of helium on the energy parameters of an electron-beam-pumped Ar-Xe laser

摘要

An investigation was made of the influence of the addition of helium on the lasing and amplifying characteristics of an electron-beam- pumped Ar-Xe laser emitting in the near-IR part of the spectrum. The efficiency of this laser was far from maximal when the pressure of the two-component laser mixture was -1 bar and the electron cur- rent density had the maximum value j-1.4 A/cm~2. A major improvement in the energy parameters was obtained by Reducing the electron current density of by adding helium to the active Medium.
