Abstract

Two-photon absorption by femtosecond laser irradiation changed the charge state of silver ions doped in sodium-borate glasses. We investigated the spectral characteristics of irradiated samples by using absorption, photoluminescence and excitation spectra. The sizes of the silver nanoparticles formed inside the glasses were estimated. We also fabricated a multilayer pattern of micro-spots to study the feasibility of three-dimensional optical memory by using femtosecond laser-induced photoluminescence change and we formed a grating to determine the change in the refractive index of the irradiated area.
