Laser Induced Rise of Luminescence Efficiency in Bi-Doped Glass

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.
