Abstract
This invention is directed toward a method of calculating the total laser energy needed to produce one or more selected laser induced surface modification reactions in a substrate moving relative to a laser beam. The present invention is further directed to a method for programming a programmable feedback control system with the calculated total laser energy such that the control system may be used to control laser beam power level and beam width in a process for producing a laser induced surface modification.
