The fight against forgery of valuable items demands efficient and reasonably priced solutions. A security tag featuring holographic elements for anti-counterfeiting is one them. However, the content colours a diffraction image that would be seen by an observer are often counterintuitive in design stage. Here, we propose original algorithm based on conical formalism, which can used to describe variations with respect all aspects observation. We validate output comparing it test holograms,...
Diffraction efficiency (DE) and laser-induced damage threshold of Chirped pulse amplification (CPA) system diffraction gratings (DGs) are one the main limiting factors for anticipated progress high peak power lasers. Optimization a reflectivity dielectric multilayer ZrO2/SiO2 stack mirror with DG etched in top SiO2 layer was carried out employing Rigorous coupled wave analysis method. Two families solutions possessing DE>0.99 over bandwidth 1030 nm wavelength ultrashort laser withstanding...
