Abstract

Lasers date back to 1960(1) which earmarked the initial operation of a ruby laser. For the following years, average laser output power remained low and, as a result, the development of materials processing applications progressed slowly. An important commercial application evolved in 1965(2) when the Western Electric Company adapted a pulsed system for production drilling of diamond wire drawing dies. In this application the processing time for drilling of a die was reduced from 24 hours for conventional techniques to less than one hour with lasers. A variety of commercial drilling applications have since been developed; one of the most successful being laser drilling of cooling passages in gas turbine parts (2,3). The success of these initial production applications hinged on the laser’s ability to accurately deliver a precisely controlled amount of energy to a highly localized region of a workpiece.
