A fiber spool offsets aggregated connector and dirty-fiber losses so a distributed Raman amplifier can keep pumping and maintain gain.
- Ghost-Pulse Supercontinuum Generation for Negative Chirp Transfer
A shorter ghost pulse imprints negative chirp on a carrier pulse, broadening supercontinuum bandwidth without longer pulses or same-frequency femtosecond lasers.
- Hollow-Core Fiber Ultrafast Laser for Few-Cycle Pulse Compression
Gas-filled hollow-core fibers generate multidimensional solitary states for tunable, high-energy few-cycle pulses without complex OPA stages.
