来源:ChineseOpticsLetters 年份:2018
With the increasing output power of the monolithic fiber laser oscillators, the stimulated Raman scattering (SRS) effect becomes one of the main limitations of power scaling. Employing fiber with a larger mode area is an effective technique......
Monolithic high-average-power linearly polarized nanosecond pulsed fiber laser with near-diffraction
[期刊论文] 作者:LongHuang,PengfeiMa,DarenMeng,LeiLi,RumaoTao,RongtaoSu,YanxingMa,PuZhou,
来源:HighPowerLaserScienceandEngineering 年份:2018
An all-fiberized high-average-power narrow linewidth ns pulsed laser with linear polarization is demonstrated. The laser system utilizes a typical master oscillator power amplifier (MOPA) configuration. The stimulated Brillouin scattering (......
Comprehensive investigation on producing high-power orbital angular momentum beams by coherent combi
