Abstract: A method for processing a transparent workpiece includes directing a pulsed laser beam into the transparent workpiece such that a portion of the pulsed laser beam directed into the transparent workpiece generates an induced absorption within the transparent workpiece, thereby forming a damage line within the transparent workpiece, and the portion of the pulsed laser beam directed into the transparent workpiece includes a wavelength λ, a spot size w0, and a Rayleigh range ZR that is greater than F D ⁢ π ⁢ w 0 2 λ , where FD is a dimensionless divergence factor comprising a value of 10 or greater. Further, the method for processing the transparent workpiece includes etching the transparent workpiece with an etching vapor to remove at least a portion of the transparent workpiece along the damage line, thereby forming an aperture extending through the at least a portion of the thickness of the transparent workpiece.

Abstract: Methods for machining glass structures may be performed on fusion-drawn glass laminates having a core layer interposed between a first cladding layer and a second cladding layer. The core layer may be formed from a core glass composition having a core photosensitivity, the first cladding layer may be formed from a glass composition having a photosensitivity different from the core photosensitivity, and the second cladding layer may be formed from a glass composition having a photosensitivity different from the core photosensitivity. At least one of the core layer, the first cladding layer, and the second cladding layer is a photomachinable layer. The methods may include exposing a selected region of a photomachinable layer in the fusion-drawn laminate to ultraviolet radiation; heating the glass structure until the selected region crystallizes; and removing the crystallized material selectively from the photomachinable layer.

Abstract: A glass laminate for an architectural element has a glass substrate coupled to the architectural element and defines a primary surface facing away from the architectural element. A phase-separable glass cladding is coupled to the primary surface. The cladding has an interconnected matrix with a first phase composition and a second phase that has a second phase composition different than the first phase composition. The second phase is distributed throughout the interconnected matrix. A copper phase is distributed within the interconnected matrix. The glass cladding has an antimicrobial log kill rate greater than about 4 as measured by an EPA Copper Test Protocol.
