Influence of the discharge tube diameter and buffer gas pressure on the afterglow process of elemental copper vapor laser

Abstract

From figures 3-4 we can see that gas temperature of gas hea is tely defined contributed into discharge tube During the working of,me por laser we need PO temperature between center pa tube increase tinder incl-eaw of Calculation spatially dependence checking for gas heating in&dly.discharge tube because increasing above optimal;valqe (for these conditioiis) brings to increasing stray population of lower metastable level. This is bringing to reducing frequen-, cy and energy parameters ofsuch lasers.1.M.J.,Brner B.E.
