Abstract
Abstract An apparatus for controlling a high power laser beam for three dimensional operation consists of a mirror and three linear servo-mechanisms to tilt and to translate the mirror. The movement of the linear servo-mechanisms is controlled by a computer numerical control system or programmable logic controller.
