Laser for 3D Glass Engraving

May 20, 2005

You may have already seen these nice little glass cubes with engraved 3-dimensional faces, animals, machines etc. They are manufactured by focusing a high power laser beam inside the glass. The energy of the laser beam causes micro explosions in the glass.

The result is small white dots, and with hundreds of these dots a 3-dimensional picture appears inside the glass.

Laser diodes are not only very expensive but also quite sensitive.

Precise output regulation is necessary to control the current into the laser diodes. Vicor’s product was an ideal solution because of its high density and adjustable output voltage.
