  1. 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泵浦方案;輻射光譜寬( 900 ~ 1200nm ) ,激光輸出可以有很寬的可調諧范圍。
