A method for cutting thin glass, wherein the thin glass is heated with a laser beam along a path forming a cutting line moving along a forward feed direction, such that a crack propagates along the cutting line and cuts through the thin glass. The laser beam is formed by a beam-forming optic in such a way that the beam profile thereof has an elongated shape. The laser beam is orientated on the surface of the thin glass such that the longitudinal direction thereof is aligned in the feed direction. The elongated shape of the beam profile is asymmetric, such that the intensity course differs at the ends of the beam profile in such a way that the increase in intensity at the front end crossing the thin glass first is steeper than the drop in intensity at the opposite rear end.
