Abstract
A method having steps of placing a glass sheet having a front surface, a reverse surface and a thickness onto a sacrificial substrate; directing a beam from a laser at the front surface and through the glass sheet; pulsing the beam at a frequency of between 10 kHz and 30 kHz, and at the sacrificial substrate; moving the beam across the glass sheet at a rate of between 30 millimeters per second and 90 millimeters per second; ablating the sacrificial substrate with the beam; generating a superheated vapor in response to the ablating of the sacrificial substrate; and ablating the reverse surface of the glass sheet with the superheated vapor, whereby the glass sheet is cut.
