Local laser-decolorizing of gamma-ray irradiated silicate glass

Local decolorizing of gamma-ray irradiated silicate glasses has been studied under thermal annealing by a laser beam. The influence of the beams exposure time was studied, showing that an increase of the glass temperature on the irradiated areas can locally induce complete decolorizing (bleaching) of glass. In this work, the heat conduction differ- ential equation is solved by numerical approach using the finite element method and results are compared by experimental analysis. Although much work is being developed in the fields of color centers creation and its decay by heat, this work presents the first systematic study on near- infrared decolorizing of gamma-irradiated float silicate glasses.
