Abstract
⺠We report emission from the femtosecond laser irradiated regions of PMMA, PDMS, PS and PVA. ⺠The cause of emission from laser modified regions is attributed to the formation optical centers. ⺠Unique excitation spectrum obtained by monitoring at different wavelengths. ⺠ESR spectrum confirmed the presence of free radicals in the irradiated regions of PMMA, PDMS, and PS.
