METHODS OF FORMING IMAGES BY LASER MICROMACHINING
Abstract:
A method and laser processing system (2) addresses a substrate (102) with three different sets of laser processing parameters to achieve different surface effects in the substrate (102). A first set of laser parameters is employed to form a recess (106) in the substrate. A second set of laser parameters is employed to polish a surface (108) of the recess (106). A third set of laser parameters is employed to modify a polished surface (108) of the recess (106) to have optical characteristics that satisfy conditions for a desirable visual appearance.
