Robust authentication through stochastic femtosecond laser filament induced scattering surfaces Academic Article uri icon

abstract

  • © 2016 Author(s). We demonstrate a reliable authentication method by femtosecond laser filament induced scattering surfaces. The stochastic nonlinear laser fabrication nature results in unique authentication robust properties. This work provides a simple and viable solution for practical applications in product authentication, while also opens the way for incorporating such elements in transparent media and coupling those in integrated optical circuits.
