Ultrafast Laser Sources
Ultrafast laser source technology is one of the most dynamic and cutting-edge frontiers in contemporary photonics. By generating extremely short pulses with durations on the order of femtoseconds (1 fs = 10⁻¹⁵ s) or even attoseconds (1 as = 10⁻¹⁸ s), it enables the precise delivery of optical energy within an extremely short time and confined spatial scale. This capability allows, for the first time, the "freezing" of atomic motions and electronic transitions in the microscopic world, and enables nearly heat-affected–free "cold" processing in material manufacturing. As a result, it has profoundly reshaped the landscape of both fundamental scientific research and high-end industrial manufacturing.
Carrier-Envelope Phase Stabilization
Achieving repeatable alignment between the pulse envelope and the peak of the carrier electric field is the cornerstone of attosecond science for exploring electron dynamics.
Laser Pump and Seed Sources
Providing the "spark" (seed) and the "power" (pump) for subsequent amplification, this determines the basic performance parameters of the system.
Optical Parametric Chirped Pulse Amplification (OPCPA)
Overcoming the constraints of conventional gain media, OPCPA delivers wavelength-tunable, high-power amplification of ultrashort pulses.
Synchrotron Locking and Synchronization
Precisely synchronizing the ultrafast laser with large-scale facilities (such as free-electron lasers) to enable pump-probe experiments.
