    Laser Etching

    We've seen the amazing work that Pete does with his laser, after the fact. But have you ever seen one in action??

    That is amazing to me. How come there is not residue, like scorch marks, burns left by that? Even in metal I would think it would need clean up of darken along the cut when done....

    I believe that is a very high power galvo laser. Even more amazing when you learn how the beam is controlled.

    Picture a high power laser beam coming at you thru a window. You have a small mirror in your hand. Now quickly move the mirror around to direct the laser beam to the work surface as needed.

    I think it is really done with a mirror that has two speaker type cones mounted on two different axis. Incredible how it can work at all never mind that fast and accurate.
