Abstract
Methods of making a glass-based article including a surface feature thereon. Methods include arranging a glass-based substrate relative to a laser. Methods also include irradiating the glass-based substrate with laser beam with a light wavelength from about 2500 nm to about 3000 nm to grow a surface feature thereon.
Claims11
A glass-based article comprising:
- a transparent glass-based substrate comprising a surface, the transparent glass-based substrate absorbs a light wavelength from about 2500 nm to about 3000 nm wherein the transparent glass-based substrate comprises:
- a hydroxyl concentration within its composition of at least 100 ppm and a transition metal ion in concentration of less than about 1.0 wt. %, and
- a laser-induced, transparent glass feature on the surface of the transparent glass-based substrate.
