Abstract
Methods of making a transparent glass-based article including at least two transparent glass-based substrates and a laser-induced bond therebetween. Methods include arranging the two transparent glass-based substrates relative to each other to form a contact area. Methods also include providing a laser beam contiguous the contact area to bond the two transparent glass-based substrates.
Claims30
An article comprising:
- a first glass-based substrate,
- a second glass-based substrate,
- the first or second glass-based substrate absorbs at a wavelength from about 2500 nm to about 3000 nm, and
- a laser-induced bond joins the first glass-based substrate and the second glass-based substrate.
1 more element
An article comprising:
- a first fused silica glass substrate comprising a hydroxyl concentration greater than about 300 ppm,
- a second glass-based substrate, and
- a laser-induced bond connects the first fused silica glass substrate and the second glass-based substrate.
A method of forming a glass-based stack comprising:
- arranging a first glass-based substrate relative to a second glass-based substrate to form a contact area,
- directing a laser beam comprising a light wavelength from about 2500 nm to about 3000 nm contiguous the contact area, and
- wherein the first glass-based substrate absorbs light from the laser beam in an amount sufficient to heat and bond the first glass-based substrate and second glass-based substrate contiguous the contact area.
