Paper Abstract

When ethylene glycol laser coolant is irradiated by ultraviolet (UV) light from a krypton gas filled titanium- or cerium-doped, fused silica envelope laser flashlamp, thermally assisted photo-oxidation of the ethylene glycol produces glycolic acid and other oxidation products. The data collected show that the laser coolant acidity depends on the type of dopant in the flashlamp envelope. The measurements show that the flashlamp envelope highly doped with cerium not only provides UV protection to the laser coolant but also provides an increase in the laser output due to the cerium fluorescence effect.
