High‐Energy Femtosecond All‐Fiber Laser Systems in 1.7–1.8 μm Using a Normal‐Dispersion Tm‐Doped Fiber

Advanced Photonics Research
A W‐type normal dispersion thulium‐doped fiber (NDTDF) is utilized to generate high average power, high‐energy femtosecond pulses at 1.7 μm region for bio‐imaging applications.

Characteristics of Q-switched cladding-pumped ytterbium-doped fiber lasers with different high-energy fiber designs

, 2001
We theoretically and experimentally analyze Q-switched cladding pumped ytterbium-doped fiber lasers designed for high pulse energies. We compare the extractable energy from two high-energy fiber designs: (1) single- or few-moded low-NA large mode area ...

Raman amplification and pulsed lasing in cladding-pumped germanosilicate fiber

We report for the first time Raman amplification in a cladding-pumped fiber. The double-clad germanosilicate fiber was pumped by a Q-switched Er-Yb co-doped fiber laser at 1570 nm. The power conversion efficiency was up to 36%, with a slope of 64%

Ytterbium-doped low-NA P-Al-silicate large-mode-area fiber for high power applications

We demonstrate an efficient, ytterbium-doped low-NA fiber with core glass containing high levels of Al2O3 and P2O5 in silica host that shows low-photodarkening and generated 175 W of continuous-wave output power with 80% laser ...
