Abstract
A process and apparatus are disclosed for accurately drilling and calibrating holes via a pulsed laser beam to form a perforated work piece. The sounds emitted by the melting of the work piece due to its contact with the laser beam are sensed, converted into digital form, compared with a reference value and are utilized to control the operating parameters of the laser.
