Method for production of laser-induced damage images with special characteristics by creating damages of special space shape

摘要

A method for production of laser-induced damage images, which are able to change their optical characteristics depending on bopresight allocation and which are looked like iridescent images laying out white light incident upon them. These images are created by laser-induced damages of special space form. These damages are produced by creation of two areas (the first and the second) surrounding the pre-set points: the first area is essentially large than the second area, having form like desirable damage. The pulse laser radiation creates under critical electron density in the first area and initiates the breakdown in the second area.
