We report refractive index change in a femtosecond laser irradiated Nd 3+ -doped phosphate glass. The effects of annealing temperature on the refractive index change of the glass have been investigated. Absorption spectra of the glass sample before and after femtosecond laser irradiation and subsequ

โฆ Synopsis
The experimental study of the color centers activation in Bi-doped boro-alumino-phosphate glass by means a femtosecond laser irradiation was performed. The data of formation rate of laser-induced absorption centers in the glass bulk are presented. As a probable mechanism of bismuth glasses photoactivation a process of structural precursors recharging is proposed. This laser microfabrication technique opens up opportunities for active photonic crystals manufacturing.
