Ultraviolet lasing on Au+ lines in an He-Au pulsedlongitudinal nanosecond discharge

摘要

The laser characteristics of a gold ion laser oscillating on then282.2-, 284.7-, 289.3-, and 291.8-nm lines are reported. The laser isnexcited in a longitudinal nanosecond pulsed discharge. Quasi-cw laserngeneration of 270-mW average output power and 33%/m small-signal gainnare obtained for the strongest line of 282.2 nm. This average outputnpower corresponds to a peak pulsed power of 3.9 W. The reported lasernpromises various prospects for scientific and technological applications
