over-doped 中文意思是什麼
over-doped
解釋
過度摻雜-
We also show that preparation methods, working parameters, substrate orientation, the type and amounts of doped ions, and annealing temperature are all exerting influences over egd. this is why different egd values are reported in literatures
另外我們還討論了e _ g ~ d值的影響因素，如制備方法、工藝參數、基體取向、摻雜離子種類、摻雜離子數量、退火溫度等等，解釋了為什麼不同文獻報道的e _ g ~ d值有所不同。 -
Ytterbium ( yb ) - doped silica fibers have a broad - gain bandwidth ( 850 ~ 1050nm ), excellent power conversion efficiency, and a broad - absorption bandwidth ( 900 ~ 1200nm ). their ability to provide amplification over the very broad wavelength range from ~ 975nm to ~ 1200nm is expected to generate increasing interest in the near future. they offer an almost ideal gain medium for the fiber lasers and fiber amplifiers that work at the wavelength around 1 m
摻鐿石英光纖具有幾個方面的優點，如能級結構簡單，與摻er3 + 、 nd3 +等稀土離子的光纖相比，不存在對泵浦光或信號光的激發態吸收（ esa ） ，可以有更高的摻雜濃度;有較寬的吸收光譜（ 850 ~ 1050nm ） ，可以利用多種泵浦光源來設計泵浦方案;輻射光譜寬（ 900 ~ 1200nm ） ，激光輸出波長可以有很寬的可調諧范圍。
