Beam quality and photodarkening comparison of tandem-pumped and directly diode-pumped ytterbium-doped fiber amplifiers被引量：1
《Chinese Optics Letters》2014年第A02期26-29,共4页于海龙 王小林 周朴 肖虎 陈金宝 
Compared with the conventional diode-pumped ytterbium-doped fiber amplifiers （YDFAs）, tandem-pumped YDFAs are regarded as a better solution for high power scaling. In this letter, we compare and analyze the two type...
Photodarkening-Induced Absorption and Fluorescence Changes in Yb Fibers被引量：1
