Cat No:PCG-0001
Pulse compression gratings are core components of Chirped Pulse Amplification (CPA) technology and are widely used in picosecond and femtosecond ultrashort-pulse laser systems. The diffraction efficiency and laser-induced damage threshold of the grating are critical to overall laser performance. Especially in ultra-intense ultrashort-pulse laser systems, the stringent requirements on diffraction efficiency, laser damage threshold, and grating size for pulse compression gratings are far beyond the capabilities of conventional commercial gratings. The pulse compression gratings provided by CIOMP (Changchun Institute of Optics, Fine Mechanics and Physics) can reach meter-scale dimensions, with an average diffraction efficiency of up to 97%.
