Method and laser system for production of high quality single-layer
laser-induced damage portraits inside transparent material
Abstract
Embodiments of methods and systems for producing high quality single-layer
laser-induced damage portraits inside a transparent material are
disclosed. One or more embodiments of the invention comprise a method and
a system for production of an etch point without focal area expansion
connected with the focused beam refraction. One or more embodiments of the
invention comprise a method and a system for producing single layer
laser-induced damage portraits based on generation of small smoothed etch
points of determined sizes and on control of their brightness without
variation of their determined sizes. According to the invention the sizes
of etch points, which can be used for reproduction of single-layer
portraits are determined; shades of gray are reproduced by controlling the
number of breakdowns and their special configurations inside transparent
area corresponding to the etch point; disposition of these breakdown
configurations inside an etch point of determined sizes is actualized by
using cumulative effects.
