Embodiments of methods and laser-computer graphics systems for producing
images such as portraits and 3-D sculptures formed from laser light
created etch points inside an optically transparent material are
disclosed. One or more embodiments of the invention comprise a method and
system for simultaneously producing one or more etch points in first and
second objects. In accordance with a method, a main beam is split into
first and second beams, each beam having an energy level greater than
that necessary to cause a breakdown in the material comprising the first
and second objects. The first and second beams are directed at focal
points within the first and second objects, generating etch points
simultaneously therein. One or more embodiments of the invention comprise
methods and systems for generating images in first and second objects. In
one or more embodiments, the images are comprised of etch points having
multiple gray shades and/or of etch points having iridescent qualities.
