    Abstract: Embodiments of methods and an apparatus for creating high quality laser-induced damage images are disclosed. One or more embodiments of the invention comprise a method for producing laser-induced images inside the special transparent material containing special kinds of impurities, which decrease the damage threshold of the material. Laser radiation is focused inside the transparent material in such a way that focal area contains at least one said impurity. Other embodiments of the invention comprise a method and a system for producing laser-induced images by using two lasers. The first laser generates radiation, which heats the predetermined material area about a point, where breakdown should be produced, to the vitrify temperature. The second laser generates radiation, which creates breakdown in a point of the heated area after the area is heated to the vitrify temperature.
