Alexander I Erokhin: Method and equipment for forming image inside transparent material by pulse laser beam. Russian Technol Group, May 30, 1995: JP1995-136782

PURPOSE: To form an image inside a transparent material by making use of a pulse laser beam. CONSTITUTION: A laser beam 3 is generated by a Q-switched laser with a limited diffraction. A small break point whose dimension is adjustable is formed at a point inside a transparent material 6 by precisely ...
