Abstract

The output powers from 25 mm (volume 0.49 1) and 40 mm (volume 1.9 1) diameter copper vapour lasers (nominally 20 and 55 W devices) are approximately doubled to > 50 and > 100 W respectively by adding small partial pressures of both H2 and HCl to the neon buffer gas. Our studies show that this gas mixture performs better than a H2-HBr admix, a result we attribute to more efficient reassociation of HCl in the plasma region.
