Passive optimization of pump noise transfer function by narrow band-pass filtering in femtosecond fi
[期刊论文] 作者：PengQin,SijiaWang,MinglieHu,YoujianSong,
来源：HighPowerLaserScienceandEngineering 年份：2019
Fluctuation of pump power is one of the major sources of temporal and intensity noise in femtosecond fiber lasers. In this work, the transfer functions between the relative intensity noise (RIN) of the pump laser diode (LD) and the output R......
Extraction of internal phase motions in femtosecond soliton molecules using an orbital-angular-momen
[期刊论文] 作者：YuweiZhao,JintaoFan,YoujianSong,UweMorgner,MinglieHu,
来源：PhotonicsResearch 年份：2020
Internal motions in femtosecond soliton molecules provide insight into universal collective dynamics in various nonlinear systems. Here we introduce an orbital-angular-momentum (OAM)-resolved method that maps the relative phase motion withi......
Ultra-broadband optical spectrum generation from a stretched pulse fiber laser utilizing zero-disper
[期刊论文] 作者：ChengZhang,LuChai,YoujianSong,MinglieHu,ChingyueWang,
来源：ChineseOpticsLetters 年份：2013
We investigate the effects of a piece of zero-dispersion fiber (ZDF) on the pulse dynamics of a passively mode-locked fiber laser operating in the stretched-pulse regime. Numerical simulation suggests that the proper location and length of ......
Generation of few-cycle laser pulses by coherent synthesis based on a femtosecond Yb-doped fiber las
[期刊论文] 作者：AichenGe,BowenLiu,WeiChen,HaochenTian,YoujianSong,LuChai,MinglieHu,
来源：ChineseOpticsLetters 年份：2019
We demonstrate a coherent synthesis system based on femtosecond Yb-doped fiber laser technology. The output pulse of the amplification system is divided into two replicas and seeded into photonic crystal fibers of two parallel branches for ......

来源：ChineseOpticsLetters 年份：2014
We demonstrate an all-fiber, high-power, and high stability ultrafast laser source operating at 1563 nm. A highly stable, self-starting carbon nanotube (CNT) mode-locked femtosecond fiber laser is used as the seed source. The amplifier stag......

来源：ChineseOpticsLetters 年份：2015
Investigations are performed to explore high-repetition-rate femtosecond laser ablation effects on the physical and chemical properties of poly(methyl methacrylate) (PMMA). A scanning electron microscopy (SEM) is used to characterize the mo......
Spectral filtering effect on multi-pulsing induced by chirped fiber Bragg grating in dispersion-mana
[期刊论文] 作者：DongyuYan,BowenLiu,DefengZou,JieGuo,YuxiChu,YoujianSong,MinglieHu,
来源：HighPowerLaserScienceandEngineering 年份：2021
We numerically and experimentally investigate the multi-pulsing mechanism in a dispersion-managed mode-locked Yb-doped fiber laser. Multi-pulsing occurs primarily owing to the inherent filtering effect of the chirped fiber Bragg grating. Th......
Large-scale absolute distance measurement with dual free-running all-polarization-maintaining femtos
[期刊论文] 作者：YuepengLi,YawenCai,RunminLi,HaosenShi,HaochenTian,MingzhaoHe,YoujianSong,MinglieHu,
来源：ChineseOpticsLetters 年份：2019
We demonstrate a robust femtosecond LIDAR setup by using two free-running environmentally stable all-polarization-maintaining nonlinear amplified loop mirror mode-locked fiber lasers. Based on the asynchronous optical sampling method, a ran......
Nonlinearity optimization of dissipative-soliton fiber laser for generation of pulses with 350 kW pe
[期刊论文] 作者：HanChi,BowenLiu,YoujianSong,MinglieHu,LuChai,WeidongShen,XuLiu,ChingyueWang,
来源：HighPowerLaserScienceandEngineering 年份：2018
We demonstrate a nonlinearity optimization method by altering distribution of passive fibers in a dissipative-soliton mode-locked fiber laser to level up output parameters. In the numerical simulation, we found that the passive fiber segmen......
High pulse energy fiber/solid-slab hybrid picosecond pulse system for material processing on polycry
[期刊论文] 作者：WeiChen,BowenLiu,YoujianSong,LuChai,QianjinCui,QingjingLiu,ChingyueWang,MinglieHu,
来源：HighPowerLaserScienceandEngineering 年份：2018
We demonstrate an all polarization-maintaining (PM) fiber mode-locked laser seeded, hybrid fiber/solid-slab picosecond pulse laser system which outputs...
Compact and high-power broadband terahertz source based on femtosecond photonic crystal fiber amplif
[期刊论文] 作者：FengLiu,XiaokunHu,JiangLi,ChangleiWang,YiLi,YanfengLi,YoujianSong,BowenLiu,MinglieHu,LuChai,QirongXing,
来源：ChineseOpticsLetters 年份：2011
We present a review of the development of a compact and high-power broadband terahertz (THz) source optically excited by a femtosecond photonic crystal fiber (PCF) amplifier. The large mode area of the PCF and the stretcher-free configurati......
