High-efficiency and high-power single-frequency fiber laser at 1.6 um based on cascaded energy-transfer pumping
Xianchao Guan, Qilai Zhao, Wei Lin +5
In this paper, a technique combing cascaded energy-transfer pumping (CEP) method and master-oscillator power-amplifier (MOPA) configuration is proposed for power scaling of 1.6-um-…
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…
Deep learning-based phase control method for coherent beam combining and its application in generating orbital angular momentum beams
Tianyue Hou, Yi An, Qi Chang +8
We incorporate deep learning (DL) into coherent beam combining (CBC) systems for the first time, to the best of our knowledge. Using a well-trained convolutional neural network DL…
Intrinsic mechanism for spectral evolution in single-frequency Raman fiber amplifier
Liu Wei, Ma Pengfei, Miao Yu +3
In this work, the spectral evolution properties in single-frequency Raman fiber amplifier (RFA) with different pump manners are analyzed theoretically for the first time based on t…
