Unveiling the temporal dynamics in multi-longitudinal mode ytterbium-doped fiber lasers
Wei Liu, Pengfei Ma, Pu Zhou +1
In this work, we propose a unified spatio-temporal model to study the temporal dynamics in continuously pumped ytterbium-doped fiber lasers (YDFLs). Different from previously repor…

Kilowatt-level Yb-Raman fiber amplifier with narrow-linewidth and near-diffraction-limited beam quality
Pengfei Ma, Yu Miao, Wei Liu +2
By focusing on a typical emitting wavelength of 1120 nm as an example, we present the first demonstration of a high-efficiency, narrow-linewidth kilowatt-level all-fiber amplifier…

Effects of four-wave-mixing in high-power Raman fiber amplifiers
Wei Liu, Pengfei Ma, Pu Zhou +1
In this work, we derive and present the coupled amplitude equations to describe the evolutions of different spectral components in different transverse modes for Raman fiber amplif…
