The infrared beam from an erbium laser is absorbed efficiently by the tooth but poorly by the gums. 来自铒激光器的红外光束能够被牙齿有效地吸收,但是牙龈却不行。
An proposal for soliton adiabatic amplification is presented that uses a erbium-doped fiber amplifier constructed from dispersion decressing fiber. 文章研究在色散渐减光纤构成的掺铒光纤放大器中的光孤子绝热放大方法。
This paper theoretically analyzes the Rayleigh backscattering of erbium-doped fiber, calculates the relation between the Rayleigh backscattering light and pump power, erbium-doped fiber length, and 本文对掺铒光纤的瑞利散射进行了理论分析,计算了后向瑞利散射光与泵浦功率、铒光纤长度、号光功率的关系,并提出了用隔离器减小后向瑞利散射光的方法。
erbium
[ noun ] a trivalent metallic element of the rare earth group; occurs with yttrium <noun.substance>
Erbium \Er"bi*um\, n. [NL. from Ytterby, in Sweden, where gadolinite is found. Cf. {Terbium}, {Yttrium}, {Ytterbium}.] (Chem.) A rare earth element of the lanthanide series associated with several other rare elements in the mineral gadolinite from Ytterby in Sweden. Symbol Er. It has atomic number 68 and an atomic weight of 167.26. The pure element is metallic with a bright, silvery luster. It is relatively stable in air, not oxidizing as quickly as some other rare earths. Its salts are rose-colored and give characteristic spectra, and the pink oxide has been added as a colorant in glass and porcelain enamel glazes. Its sesquioxide {Er2O3} is called erbia. --HCP61 [1913 Webster +PJC]
However, erbium amplification is targeted for future long-distance fiber-optic communication systems operating at wavelengths of 1.5 microns.
