Title: Photoacoustic study on photobleaching of Rhodamine 6G doped in poly(methyl methacrylate)
Author: Radhakrishnan, P; Girijavallabhan, C P; Nibu, A George; Aneeshkumar, B
Abstract: The photobleaching of the lasing dye Rhodamine 6G embedded in the solid matrix poly(methyl methacrylate) was investigated using a photoacoustic technique. Chopped laser radiation from an argon ion laser at four different wavelengths was used for the study. Experimental results indicate that the photobleaching rate is directly proportional to the incident laser power while it decreases with increase in concentration of the dye molecules. In the present case we have not observed any dependence of photobleaching on the chopping frequency. One-photon absorption is found to be responsible for the photobleaching of the dye within the selected range of laser power.
