Diffraction gratings are fundamental optical components that manipulate light through periodic micro- or nano-scale structures to achieve wavelength dispersion, beam shaping, and spectral control. By precisely engineering groove profiles and spacing, diffraction gratings enable high efficiency, accurate spectral resolution, and tailored dispersion performance across a wide wavelength range. They are widely used in laser systems, spectroscopy, optical communication, and advanced scientific instrumentation, serving as key elements in both free-space and integrated photonic applications.

Pulse-compressed gratings are essential components in chirped pulse amplification (CPA) systems, enabling the recompression of temporally stretched ultrashort laser pulses back to their original duration. They are optimized for high diffraction efficiency, precise dispersion control, and ultra-high laser damage thresholds, ensuring stable operation under extreme peak power conditions. These gratings play a critical role in maintaining pulse quality and maximizing output performance in femtosecond and picosecond laser systems.
