Holographic gratings can now reach one meter in length. This is a unique technological achievement. HORIBA is the only company to produce and market such gratings. They feature the latest generations of lasers: ultra-short pulse lasers designed according to the principles of CPA (Chirped Pulse Amplification), developed by Gérard Mourou and Donna Strickland, winners of the Nobel Prize in Physics in 2018, which reach powers of several petawatts.
