摘要：Apparatus for laser processing, such as drilling of a workpiece, optionally has anoptical fiber and output coupler for applying laser light to machine a workpiece andcause it to vibrate. An acoustic sensor is mounted on the workpiece, and a determiningmeans, such as a computer, determines when the vibrations change, such as when theycease. The information can be used to change the laser pulse power and duration and therelative distance of the laser focal plane on the workpiece. A method of laser processinga workpiece causes vibrations in the workpiece by applying laser light to it, monitors thevibrations, and determines when they change.
