Methods and systems of laser-induced image technology and ways of their development are discussed. The methods depend on kind of laser-induced etch points (marks), which are used for image creation. Today, the marks, which are usually used for this purpose, are laser-induced damages which are a result of breakdown phenomena. Corresponding systems comprise the following subsystems: A) laser system for generating laser-induced damages inside a transparent material so as the exterior light scattered from them has low fluctuations; B) computer graphic system for transformation of an image into arrangement of points at which breakdowns should be produced; C) systems for controlling characteristics of laser-induced images including the number of gray shades, image resolution, color deviation and so on; D) systems for controlling parameters of laser radiation including direction of laser beam. The methods and systems for increasing quality of such images are discussed. However, there are also other marks appearing as a result of photo ionization and of other physical phenomenon, accompanying interaction of power laser radiation with transparent material. The use of these marks opens new opportunities for creation of laser-induced images with special characteristics. These opportunities are also subject of our discussion.
