【摘要】 掺稀土碲酸盐玻璃是宽带光纤放大器的一种非常重要的材料,具有传送区域宽、玻璃稳定性好等特点。讨论了在980nm光泵浦的条件下,碲酸盐玻璃中稀土离子Pr3+、Er3+的发光寿命。在发光寿命的测量中,采用100MHz数字示波器来监测荧光的衰减,并将测得的衰减数据经最小二乘法拟合算得发光寿命。更多还原

【Abstract】 Tellurite glass doped rare earth is a kind of important material used in fabricating broadband fiber amplifiers. It has the properties of wide transmission region, good stability and so on. We discussed the radiative lifetimes of rare earth ions(Pr³⁺,Er³⁺) in tellurite glasses while the diode-pumped laser is at 980nm. We selected a 100MHz digital oscilloscope to monitor the fluorescence decay in the radiative lifetime measurement and calculated the radiative lifetime with the dacay data obtained from the oscilloscope through the fitting calculation of the least square method.更多还原
