Abstract

Picosecond and femtosecond laser induced darking in some optical glass were studied. Absorption spectra of the original and irradiated glasses were measured. It is believed that the darking was induced by color center generation. The mechanism of the color center generation was demonstrated. Darking area disappeared after heat treatment under 200℃ for a few minutes.
