A 60-W high-beam-quality single-oscillator copper vapor laser

摘要

We report dramatic improvements (up to four times) in thengeneration of high-beam-quality (HBQ) output power from copper vapornlasers (CVLs) by using tailored HCl-H2-Ne buffer gasnmixtures. Up to 60 W of HBQ power was obtained from a 38-mmnbore-diameter CVL at a pulse repetition frequency of 12 kHz and 50 W atn22 kHz. This improvement in power capability is attributable to thenmodification of the spatio-temporal gain characteristics of the lasernwhen using the new buffer gas mixture
