Abstract
We report efficient operation of a longitudinal discharge‐excited Sr+ recombination laser operating at λ=430.5 nm in a ‘‘long pulse’’ (∼1 μs full width at half‐maximum) mode which utilizes Sr++ ions produced in the afterglow by heavy body processes. Optimum operating conditions have been established and compared with those for the ‘‘short pulse’’ (∼200 ns full width at half‐maximum) mode of operation observed previously. Single pulse energies at 180 and 250 μJ have been obtained in the short and long pulse modes respectively corresponding to extraction energy densities of 6 and 8 μJ/cm3.Keywords
