Drilling, Marking And Other Applications For Industrial Nd:YAG Lasers

Examples of commercial Nd:YAG systems and their applications in industrial trimming, marking, and drilling are described. Drilling requirements are related to laser variables including pulse energy and duration, number of pulses, focussing parameters, and output beam quality. Performance of Nd:YAG, Nd:Glass, and face pumped TIR slab geometry lasers are compared. As an example of significantly improved beam quality in a high power Nd:YAG drilling laser, Coherent General's new EVERPULSETM M34 is described. The review concludes with current examples and future trends in industrial laser drilling systems and applications.
