Claim Text:
1. A method for cutting thermally-strengthened glass, comprising: providing a thermally-strengthened glass substrate wherein the thermally-strengthened glass substrate has a first surface and an opposing second surface; applying laser energy to the thermally-strengthened glass substrate under conditions effective to cut the thermally-strengthened glass substrate, wherein applying laser energy comprises: focusing the laser energy at a first position on or in proximity of the first surface; and pulsing the laser energy for a pulse duration ranging from about 10 femtoseconds to about 100 picoseconds at a pulse frequency ranging from about 100 kHz to about 100 MHz, the pulsed laser energy having a pulse energy of about 1 μJ to about 400 μJ, and having a wavelength of about 250 nm to about 1100 nm; and wherein the laser energy forms a filamentation pattern defined by a series of regularly recurring substantially parallel filamentation traces in the thermally-strengthened glass substrate.
