Patent Images

1. A method for creating of laser-induced damage images with reduced sharp star structure comprising:

  • production of the special transparent material by introducing special kinds of impurities;

    generating laser radiation and focusing it at predetermined points of said material so that the focal spot area contains at least one said impurity and laser energy exceeds the damage threshold of said material with said impurities at said focal area by a negligible amount.
