ABSTRACT
The photostability of Rhodamine 590 perchlorate laser dye in various concentration mixture ratios of Rhodamine 590 perchlorate and Vinyl acetate polymer solutions has been measured to determine the longevity of laser operation when pumped by the second harmonic of a Q-switched Nd:YAG laser. Vinyl acetate polymer solution was prepared in methanol and was used as triplet quencher additive to improve efficiency and photostability performance. Higher efficiency and photostability were obtained at low ratio of Vinyl acetate polymer solution used as additive compared with pure dye. Maximum efficiency of 45 % with photostability of 165 GJ/mol was recorded and discussed. This paper identifies new additive material that could be used for improving photostability and efficiency of Rhodamine dye.
