Abstract
A process of forming an identification marking within article formed from an at least partially optically transparent material for identification and validation, said process including the steps of (i) forming an indicia with an at least partially optically transparent material by way of subsurface laser engraving (SSLE); and (ii) forming a plurality of defects within or adjacent indicia within said at least partially optically transparent material resultant of the step of forming the indicia and from localized heating and irregularities in said at least partially optically transparent material, wherein said plurality of defects forms said identification marking.

A process of forming an identification marking within article formed from an at least partially optically transparent material for identification and validation, said process including the steps of:
- (i) forming an indicia within an at least partially optically transparent material by way of subsurface laser engraving (SSLE);
- and
- (ii) forming a plurality of defects within or adjacent said indicia within said at least partially optically transparent material resultant of the step of forming the indicia and from localized heating and irregularities in said at least partially optically transparent material;
- wherein said plurality of defects forms said identification marking.
A process of forming an identifiable marking to an article within an at least partially optically transparent material for identification and validation, said process including the step of:
- (i) forming a covert laser readable (CLR) image with an at least partially optically transparent material by way of subsurface laser engraving (SSLE);
- wherein the CLR image provides holographic projectable image such that upon a laser light source at an appropriate angle of incidence being applied to a first side of the article and through the at least partially optically transparent material, and the light exiting a second side of the article through the at least partially optically transparent material towards a viewing panel, requisite holographic image is projected on the viewing panel.
