Abstract
Creation of laser-induced damage imags inside transparent materials is one of the technical and art applications of laser induced damage phenomena. The purpose of the paper is to present the laser induced damage image technology and to discus problems of the optimization of the system producing the images. At the beginning a brief historical overview and patent situation are presented. An exemplary block-diagram of laser etching system for simultaneous production of several images inside several articles is shown and some peculiarities due to specific formation of laser induced micro-damages are discussed. Several methods for generating 3D images and portraits allowing reproduction of them within an optically transparent materials with the same resolution like computer processed images, without sharp to point structure and without significant fluctuations of gray shades are disclosed. Technique of image reproduction without undesirable regular arrangement of etch points is presented.
