Abstract

A method and apparatus of generating a laser pulse of a desired energy and micro-machining a substrate using the laser pulse. A beam of light is provided from a laser source. The beam is directed via a modulator to produce an output laser pulse with a portion of the laser pulse being used to determine the energy of the laser pulse. The modulator is controlled so as to switch off the output laser pulse when the determined energy of the output laser pulse reaches a threshold value. The output laser pulse is steered to a substrate for micro-machining.
