METHOD FOR PRODUCING ALIGNED LINEAR BREAKING POINTS BY ULTRA-SHORT FOCUSSED, PULSED LASER RADIATION; METHOD AND DEVICE FOR SEPARATING A WORKPIECE BY MEANS OF ULTRA-SHORT FOCUSSED LASER RADIATION USING A PROTECTIVE GAS ATMOSPHERE

摘要

A method is provided for preparing transparent workpieces for separation. The method includes generating aligned filament formations extending transversely through the workpiece along an intended breaking line using ultra-short laser pulses.
