We report efficient operation of a longitudinal discharge-excited Sr/sup +/ recombination laser operating at lambda = 430.5 nm in a ''long pulse'' (approx.1 ..mu..s full width at half-maximum) mode which utilizes Sr/sup + +/ ions produced in the afterglow by heavy body processes. Optimum operating conditions have been established and compared with those for the ''short pulse'' (approx.200 ns full width at half-maximum) mode of operation observed previously. Single pulse energies at 180 and 250 ..mu..J have been obtained in the short and long pulse modes respectively corresponding to extraction energy densities of 6 and 8 ..mu..J/cm/sup 3/.
