  Laser Cubes Beautiful laser cut cubes of solid crystal with designs embedded. Points inside the glass are tiny fractures, approximately .1mm in size created by a focused laser beam.The conical beam, with a focal point of about 3" shines into the crystal without damaging it except at the focal point. At that one point, the concentrated energy heats the glass causing the microfracture. The laser is pulsed off and on reflecting onto a computer-controlled mirror that moves between pauses. In some designs there could be 100,000to 400,000 points of fractures. These are available in a variety of themes. They are beautiful when placed on a lighted base. Great as a desk ornament or paper weight.
