Abstract: Laser cutting a metal foil by providing a polymer film as a carrier layer for the metal foil where the metal foil is ablated by the laser beam wavelength selected for laser cutting and wherein the polymer film is a polymer film that is transparent to the laser beam wavelength selected for laser cutting such that laser cutting produces metal foil cut parts in a substrate while the polymer backing remains intact for supporting the cut parts for subsequent separation of the cut parts from substrate.

Abstract: A laser system and method is used to micro-drill a web producing holes of approximately 85 ?m or less. The laser system comprises a laser beam having a wavelength in the range of approximately 2 to 6 microns and the focal point of the laser beam being steered onto a surface of the moving web wherein the web is moving.. The web is a film such as a flexible film or commercial packaging film. The laser beam wavelength and constant laser energy can be used to laser micro-drill the flexible film.
