Broadband Pulse Compression Grating

Cat No:PCG-0002

Description

Broadband Pulse Compression Gratings are key components in chirped pulse amplification (CPA) systems, specifically designed for the compression of ultrashort laser pulses with broad spectral bandwidths. They are widely used in femtosecond and sub-femtosecond laser systems, where maintaining high pulse quality and temporal contrast is critical. To support broadband operation, these gratings are optimized to provide high diffraction efficiency over a wide wavelength range while preserving precise dispersion control. At the same time, they feature an ultra-high laser-induced damage threshold, enabling stable operation under high peak power and high average power laser conditions. Compared with conventional commercial gratings, broadband pulse compression gratings meet far more stringent requirements in terms of diffraction efficiency, damage threshold, spectral bandwidth, and aperture size. Advanced fabrication technologies allow for large-aperture designs, including meter-scale dimensions, making them well suited for ultra-intense ultrashort-pulse laser facilities. Broadband pulse compression gratings are essential components in high-power femtosecond laser systems, petawatt-class lasers, and advanced scientific applications such as high-field physics, laser-plasma interaction, and attosecond science.
