Abstract
A method for separating an ultrathin glass using ultrashort laser pulses of an ultrashort pulse laser includes focusing the ultrashort laser pulses into the ultrathin glass such that a resulting focal zone is elongated in a beam direction and extends over an entire thickness of the ultrathin glass. The ultrashort laser pulses have a non-radially symmetric beam cross section perpendicular to a beam propagation direction. The method further includes introducing material modifications into the ultrathin glass along a separating line using the ultrashort laser pulses focused into the ultrathin glass, and separating the ultrathin glass along the separating line.
