Abstract:

This invention relates to a device and method of laser drilling and cutting. More particularly, to a laser device using both a Q-switch and essentially continuous-wave output to cut or drill metal. An object of the invention is to provide a device and method of laser drilling and cutting that has an increased efficiency. Another object of the present invention is to provide a laser cutting or drilling device that outputs both a free-running and Q-switched energy beam. A further object of the instant invention is to provide a laser cutting and drilling device comprising readily available commercial parts. Still another object of the invention is to provide a method of laser cutting and drilling of highly conductive metal workpieces without gas assist. Patent applications. JES
