Laser Coating Removal

Abstract

A system and method of using a laser is provided for removing coatings from a substrate. The frequency of the laser pulses can be determined based on the properties of heat conduction with a periodically varying temperature as a boundary condition. Accordingly, a thermal penetration depth varies with the thermal diffusivity of the coating and the angular frequency of the temperature-based boundary condition. The heating effect of the laser is confined to the coating without extending into the underlying substrate. Thus, the system and method described herein provide a way of controlling a laser for the removal of a coating.
