Abstract
A method for releasing trialkylamines into the dye circulation stream of a dye laser and a filter cartridge containing a resin bound anion stabilizing agent for insertion into the dye circulation stream of a dye laser improves the performance thereof, especially with respect to excimer and flashlamp pumped coumarin and carbostyryl dye lasers. The resin bears quaternary ammonium groups, and borohydride, bromide, hudroxide or chloride may be used as the counter ion. A resin bound borohydride stabilizing agent is capable of releasing trialkylamine into the dye circulation stream and reducing the carbonyl functional groups of polyarbonyl material in the stream to less light absorbing alcohol functional groups. A resin bound chloride stabilizing agent is capable of releasing trialkylamine into the dye circulation stream as a quencher and radical scavenger.
