In this paper effect of the pulsed CO2 laser irradiation on the optical properties of PMMA films was investigated. PMMA thin films with thickness of about 100 micron was prepared by casting PMMA solution (50 gr PMMM in 1cc toluene) on microscope glass. The samples were irradiated by a pulsed CO2 laser with 100 ns pulse duration. Effect of the irradiation parameters including the laser fluence and the number of pulses on the optical properties of the films was examined. Scanning electron microscopy and UV-Vis spectroscopy were used for the investigation of the morphology and optical changes after irradiation.
