Abstract
There are disclosed compounds for assisting triplet absorption in a laser, such as a pulsed-dye laser, the compounds comprising at least one molecule chosen from nitroxides and nitrones. In one embodiment, the disclosed compounds may be mixed with the dye of a dye laser in an amount sufficient to assist in triplet absorption. In one embodiment, the nitroxide compound comprises tempol[4-hydroxy-2,2,6,6-tetramethyl-piperidinyloxy, free radical]. Also disclosed are methods of using the disclosed compounds to control the triplet absorption of a dye laser or improve the performance or life span of a gaseous or solid laser.
