A laser beam scanner for drilling holes in various materials is provided and comprises a carbon dioxide laser beam and two rotating prisms which are rotating at different rates along perpendicular axes. The described laser beam scanner permits a much greater throughput than the XY translation table systems of the prior art by substantially reducing the rate limiting movement of the XY translation table system. One embodiment of the laser beam scanner is shown in the figure. A carbon dioxide laser beam 10, which is capable of drilling high quality holes in material 15, is directed through rotating prisms 20 and 30. Each prism provides unidirectional scanning of the laser beam.
