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......

来源：ChineseOpticsLetters 年份：2019
We report a hybrid femtosecond laser system based on a femtosecond Yb-doped fiber laser and a Yb-doped potassium gadolinium tungstate (Yb:KGW) regenerative amplifier. To match the central wavelength of the seed source, a Yb:KGW crystal is u......
Generation of few-cycle laser pulses by coherent synthesis based on a femtosecond Yb-doped fiber las

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 ......
Large-scale absolute distance measurement with dual free-running all-polarization-maintaining femtos
