A Fast Solution of the Dynamic Rate Equation for a High-Power Fiber Laser Open

Lei Duan, Runqin Xu, Shudan Tan, Xiongxin Tang, Fanjiang Xu · 2024

In the study of dynamic behaviors, such as nonlinear effects, power evolution, and pulse evolution of light in fiber gain media, solving dynamic rate equations in fiber laser systems is involved, which is computationally intensive and dire…

Theoretical model and numerical study of effect of target reflected light on high-power fiber laser Open

Lei Duan, Runqin Xu, Yun-Bo Song, Shu-Dan Tan, Cheng-Bin Liang , et al. · 2023

In a high-power fiber laser system, the reflected light generated when the laser hits the target may be recoupled to the laser and amplified by the laser, thereby damaging the laser system. This situation is particularly serious for a high…

Simulation for Generation of Several Types of Pulses in an Yb-Doped Mode-Locked Fiber Laser Open

Youshuo Cui, Jinrong Tian, Zikai Dong, Runqin Xu, Zexin Zhang , et al. · 2020

We numerically demonstrated six types of pulses in an Yb-doped fiber laser, including dissipative soliton (DS), dissipative soliton resonance (DSR), multipulse, noise-like pulse (NLP), breathing soliton and soliton explosion. The influence…

Impact of spectral filtering on pulse breaking-up and noise-like pulse generation in all-normal dispersion fiber lasers Open

Runqin Xu, Fanjiang Xu, Yanrong Song, Lei Duan, Yunbo Song , et al. · 2020

Based on mathematic simulations, the impact of spectral filtering on pulse breaking up and noise-like pulse generation in all-normal-dispersion fiber lasers are investigated. Three types of spectrum filters are employed in the simulations,…

Noise-like pulse with a 690 fs pedestal generated from a nonlinear Yb-doped fiber amplification system Open

Zexin Zhang, Jinrong Tian, Changxing Xu, Runqin Xu, Youshuo Cui , et al. · 2020

Noise-like pulses having a pedestal of 690 fs and a spike of 59.6 fs were generated in a nonlinear Yb-doped fiber amplification system. The seed source is a mode-locked Yb-doped fiber laser by nonlinear polarization rotation, and dissipati…

Generation of noise-like pulses with a 920 fs pedestal in a nonlinear Yb-doped fiber amplifier Open

Changxing Xu, Jinrong Tian, Runqin Xu, Yunfeng Wu, Luyao Fan , et al. · 2019

We demonstrate the compression of noise-like pulses in an Yb-doped fiber master-oscillator power-amplifier (MOPA). The seed source of the MOPA is an NPR mode locked fiber laser delivering 5.94-ps dissipative soliton pulses with a repetitio…

Analysis of Bound-Soliton States in a Dual-Wavelength Mode-Locked Fiber Laser Based on Bi2Se 3 Open

Kexuan Li, Yanrong Song, Jinrong Tian, Heyang Guoyu, Runqin Xu · 2017

Wavelength switchable and dual-wavelength soliton operations are demonstrated in an erbium-doped fiber laser with three pieces of TI Bi₂Se₃ polyvinyl alcohol (Bi₂Se₃-PVA) film. Wavelength switcha…
