铒离子 meaning in Chinese
erbium ion
Examples
- In the investigations of the nanosized zirconia powders co - doped with yb3 + - 0 . 2 ( 0 . 4 , 1 ) mol % tm3 + ions under 980nm ld excitation , the blue up - conversion emission at 474nm comes from the 1g4 - 3h6 transition
详细研究了铒离子掺杂二氧化锆纳米材料的上转换发光性质，得到：在低掺杂浓度(不大于1mol )下，铒离子主要发绿光。 - Phosphate glass is an ideal material for high erbium - doped . erbium ion has large emission section in phosphate glass , however , it has small absorb section for 980nm pump light , which can be settled via doped yb3 +
虽然铒离子在磷酸盐玻璃中具有较大的发射截面,但对波长为980nm泵浦光来说,其吸收截面较小,可用镱离子与之掺杂来补充这一不足。 - The cluster parameter k is presented to reduce upconversion , and the smaller the k , the lower the upconversion . another method to reduce upconversion is to dope al and p together , which can make the esa spectra shifted toward short wavelength
总结了两种抑制上转换发光的方法,即:改善掺铒光纤的团簇结构参数k , k越小,上转换发光效率越低; al / p共掺,使铒离子esa吸收谱往短波方向偏移。 - But for the final energy structure of er3 + , property of edfa ' s gain has its inherent disadvantage : edfa ' s gain is different vs wavelength , in other words , its gain spectrum is not ideally flat , so the output signal will be different if the input signal have the same power
但是由于edfa中工作物质铒离子能级结构的影响， edfa对光信号的放大特性也有其固有的缺陷： edfa对不同波长的光信号的增益并不完全相同，即其增益谱不平坦，因此一组强度相同的光信号经过放大后的强度会有所不同而产生偏差。 - Because power management in this thesis aims at amplified spontaneous emission noise of erbium ? oped fiber amplifier ( edfa ) , the thesis introduces the simplified stark ? split energy levels of er3 " , amplified working mechanisms of er3 * and working performance of edfa in details
因为本文所采用的功率管理主要是针对edfa掺饵光纤放大器所产生的自发辐射噪声去采取均衡措施，所以论文中详细介绍了edfa中铒离子的stark分裂的简化的能级模型、铒离子的放大工作机理及edfa的工作特性。
