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.
Claims21
A method of forming a feature on a glass-based article, the method comprising:
- arranging a transparent glass-based substrate relative to a laser, the transparent glass-based substrate comprising a hydroxyl concentration within its composition of at least 100 ppm;
- directing a laser beam comprising a light wavelength from about 2500 nm to about 3000 nm from the laser to contact the transparent glass-based substrate;
- and
- moving the laser beam along a surface of the transparent glass-based substrate;
- wherein the transparent glass-based substrate absorbs light from the laser beam in an amount sufficient to heat and grow a glass feature from the transparent glass-based substrate;
- wherein the transparent glass-based substrate comprises an iron ion concentration of less than about 1.0 wt. %.
