ABSTRACT:
Transparent media having high hardness and poor light absorption is cut or scribed with characters or figures by a laser beam. The method includes forming a support of a medium which is a good absorber of a laser beam, and placing the transparent medium on the support, and focusing the laser beam onto the support through the transparent medium while the transparent medium and the laser beam are moved relative to each other. A flame is generated between the support and the transparent medium to machine the transport medium, allowing it to be cut or scribed with characters or figures.
