ABSTRACT:
A method and an apparatus for creating laser-induced images inside transparent materials and on their surfaces are disclosed. The method is founded on the production of etch points by creating breakdowns at the predetermined points inside transparent material and by creating breakdowns at the predetermined points of the air or another environment. Mark areas on the transparent material surfaces are the frost areas and a surface image is an arrangement of the frost areas of different density. Such frost areas on the surface of a transparent material are produced by the plasma generated during breakdowns. A method and a system for controlling characteristics of plasma generated during breakdowns for controlling the parameters of the frost areas arisen under interaction of the plasma with the surface of the transparent material are disclosed.
