Highly efficient continuous-wave mid-infrared generation based on intracavity difference frequency m
[期刊论文] 作者：ChengXi,PengWang,XiaoLi,ZejinLiu,
来源：HighPowerLaserScienceandEngineering 年份：2019
We report on a new scheme for efficient continuous-wave (CW) mid-infrared generation using difference frequency generation (DFG) inside a periodically poled lithium niobate (PPLN)-based optical parametric oscillator (OPO). The pump sources ......

We report on the high-power amplification of a 1064 nm linearly polarized laser in an all-fiber polarization-maintained master oscillator power amplifier, which can operate at an output power level of 1.3 kW. The beam quality (...

We report the experimental study on mode instabilities (MI) in large mode area step-index fibers by testing a 30/400 mm step-index fiber in a single-pass co-pumped all-fiberized amplifier, delivering up to ~550 W of extracted output power w......
Bursts with shape-alterable pulses in a compact Tm-doped fiber laser with simultaneous active intrac
[期刊论文] 作者：XiongWang,PuZhou,XiaolinWang,HuXiao,ZejinLiu,
来源：PhotonicsResearch 年份：2014
We present a compact Tm-doped fiber laser (TDFL) to generate pulse bursts at 1.92 μm based on phase and intensity modulations. A phase modulator (PM) and an intensity modulator (IM) were included in the linear TDFL cavity to perform the si......
Coherent polarization beam combining of four polarization-maintained f iber amplif iers using single
[期刊论文] 作者：PengfeiMa,PuZhou,YanxingMa,RongtaoSu,ZejinLiu,
来源：ChineseOpticsLetters 年份：2012
In this manuscript, coherent polarization beam combining of four polarization-maintained fiber amplifiers is demonstrated. In each fiber amplifier, two cascaded fiber amplification stages are used to boost the output power to watt level. Th......

In this paper, we experimentally investigated the extreme frequency shift in high-power Raman fiber laser (RFL). The RFL was developed by using a pair of fiber Bragg gratings with fixed and matched central wavelength (1120 nm) combined with......

Stimulated Raman scattering (SRS) effect is considered to be one of the main obstacles for power scaling in general-type fiber lasers. Different from previous techniques that aim at suppressing SRS, nonlinear fiber amplifier (NFA), which ma......
High power all-fiberized and narrow-bandwidth MOPA system by tandem pumping strategy for thermally i
[期刊论文] 作者：PengfeiMa,HuXiao,DarenMeng,WeiLiu,RumaoTao,JinyongLeng,YanxingMa,RongtaoSu,PuZhou,ZejinLiu,
来源：HighPowerLaserScienceandEngineering 年份：2018
An all-fiberized and narrow-bandwidth master oscillator power amplification (MOPA) system with record output power of 4 kW level and slope efficiency of 78% is demonstrated. Tandem pumping strategy is tentatively introduced into the narrow-......
