SCULPTURING DEVICE FOR LASER BEAMS

摘要

A system and device for sculpturing a laser beam along a laser axis to a target upon command using a device (17) between the laser source (11) and the target (23) The device includes an adjustable iris aperture (19) perpendicular to the axis. A controller adjusts the aperture and the door to sculpture the laser beam in a predetermined pattern. The controller also controls the laser to direct a laser beam on a target in the predetermined pattern which may be pulsed, the duration and intensity of the pulses being controlled by the controller. An encoder (41,49) locates the iris and the door with respect to the axis for comparison of the positions with the predetermined pattern period. The device is rotatable in clockwise and counterclockwise directions by at least 180 degrees. A computer (27) is preferably used to control the positions of the iris and the door means.
