Methods of cutting glass using a laser

A method of separating a strengthened glass article comprising:

• translating a laser beam relative to a first surface of strengthened glass article, the laser beam comprising a beam waist having a center, wherein:
• the laser beam is a pulsed laser beam, said laser beam operates at a wavelength from 350 nanometers to 619 nanometers and has a pulse duration from 1 nanosecond to 50 nanoseconds;
• the strengthened glass article has a thickness of not greater than 1.1 mm and comprises a first strengthened surface layer and a second strengthened surface layer under a compressive stress and extending from a surface of the strengthened glass article to a depth of layer, and a central region between the first strengthened surface layer and the second strengthened surface layer that is under tensile stress;
• the center of the beam waist of the laser beam is positioned at or below a second surface of the strengthened glass article such that the laser beam passes through a thickness of the strengthened glass article;
• the laser beam ablates the second surface of the strengthened glass article to create a plurality of defects that extend from ablated regions on the second surface of the strengthened glass article;
• the plurality of defects defines one or more score lines along the strengthened glass article;
• at least a portion of the plurality of defects extends a distance greater than the depth of layer of the strengthened glass article;
• and
• the plurality of defects creates a crack that propagates within the glass article such that the strengthened glass article separates along the one or more score lines.

A glass article comprising:

• a first surface and a second surface separated by a thickness t that is not greater than 1.2 millimeters;
• an edge joining the first surface and the second surface;
• and
• a plurality of defects at the edge that extend from the first surface or the second surface of the glass article through a portion of the thickness t of the glass article, wherein:
• the plurality of defects extends into the thickness t of the glass article;
• individual defects of the plurality of defects are non-orthogonal to the first surface or the second surface and the plurality of defects are voids and cracks;
• and
• the individual defects of the plurality of defects are biased in a direction along the edge.
