Large-Chirp Mode-Locking Device for Ultrafast Lasers
Conventional low-chirp fiber gratings have narrow bandwidths and high dispersion due to limits on their chirp coefficients, so they generally cannot serve as broadband filters. High-chirp gratings have wider bandwidths and lower dispersion, making them convenient for broadband filtering, amplifier noise suppression, gain flattening, and fiber sensing. Fiber-grating dispersion compensation is attracting increasing attention. Using large fiber gratings for dispersion compensation (pulse stretching/compression) is a core technology in ultrafast lasers and has become an important application direction for high-chirp fiber gratings.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
