<p>The invention describes a method for the production of a dividing gap (4) in a glass pane (3) with a ray bundle (2) from a source of high energy radiation, in particular laser radiation, in which the beam of light (2), by penetrating from a first surface (6) of the glass pane (3) one or more times to a second surface (7) of the glass pane (3) which is opposite to and at a distance from the first surface, heats the glass pane (3) locally, and the resulting thermal stresses thereby open the dividing gap (4) in the glass pane (3). Thus the ray bundle (2) is introduced into the first surface, substantially free of reflection and refraction.</p> |
