- Abstract
This research work focuses on investigating the darkening phenomenon in soda-lime glasses caused by the formation of color centers when exposed to infrared femtosecond laser radiation. The study examines the kinetics of color center generation and thermal relaxation, with a particular emphasis on the influence of storage temperature. Additionally, the changes in transmittance and refractive index values of darkened glass were measured based on different laser processing parameters. The darkening process can be utilized for the creation of halftone monochrome images for decorative purposes. The study also discusses the achievable contrast values and their degradation over time. Our findings were supported by direct laser writing of an image into the glass volume, highlighting their practical interest.
