Abstract
A laser-based coating removal method debonds a film from a substrate rather than ablating the film. A laser light is transmitted through a transparent film to an underlying bonding layer for bonding the film to one or more additional films and/or a substrate. The laser light is absorbed at the bonding layer and the transparent film is released. In some embodiments, after the transparent film is released it is able to be physically removed.
