High density galvo housing for use with multiple laser beams

A multi-galvo housing system comprising:

• A metal block machined to house at least two galvo systems therewithin wherein each galvo system comprises at least one mirror and a corresponding motor for steering said mirror and wherein each galvo system is configured to steer a laser beam, each laser beam from a minimal wattage, at 1000 watt power or greater, and wherein the block keeps the galvo systems sufficiently aligned so as to concurrently direct at least two laser beams from the at least two galvo systems within the block and the at least two laser beams onto a work piece to process the work piece in a selected manner, the metal block controlling mechanical stability and heat build-up sufficiently to avoid distortion of the block and to maintain alignment of the at least one mirror of each galvo system within the block for laser processing, and
• wherein the block has no substantially closed or full internal wall or partitions between adjacent galvos.
