中文摘要采用高温熔融法制备了不同浓度Er~(3+),Er~(3+)/Pr~(3+)共掺的60TeO_2-30WO_3-10La_2O_3玻璃。研究了玻璃的红外透过光谱,吸收光谱以及在980nm LD抽运下的荧光光谱和Er~(3+:4) I_(13/2)能级荧光寿命。根据红外光谱计算了玻璃中OH~-的吸收系数alpha。应用Judd-Ofelt理论计算了J-O 参量,自发辐射系数A_(rad),荧光分支比beta;利用 Fuchtbauer-Laderburg理论计算了2.7 mum受激发射截面。分析了980nm 抽运时Er~(3+)/Pr~(3+)共掺的能量转移过程。计算得到OH~-吸收系数alpha为0.57 cm~(-1),2.7 mum自发辐射系数A_(rad)为60.6 s~(-1),荧光分支比beta为16.3%,最大受激发射截面达到1.13*10~(-20) cm~2。结果表明,这种碲酸盐玻璃适合作为获得2.7 mum输出的激光材料。
英文摘要Er~(3+) singly doped and Er~(3+)/Pr~(3+) co-doped tellurite glasses 60TeO_2-30WO_3-10La_2O_3 are prepared by conventional melting method.The fluorescence spectra and lifetime of Er~(3+ :4)I_(13/2) level pumped by 980 nm laser diode(LD)are investigated.The infrared and absorption spectra are measured.The absorption coefficientalphais calculated based on the infrared spectrum.The spontaneous radiative coefficient A_(rad) and fluorescence ratiobetaare acquired by Judd-Ofelt theory.Fuchtbauer-Laderburg theory is applied to calculate the stimulated emission cross section around 2.7 mum.The energy transfer processes and spectroscopic properties of Er~(3+)-doping and Er~(3+)/Pr~(3+) codoping are analyzed under 980 nm LD excitation.The calculated absorption coefficient alpha of OH~- is 0.57 cm~(-1), the spontaneous radiative coefficient A_(rad), fluorescence ratio beta and the maximum stimulated emission cross section of Er~(3+4) I_(11/2) to ~4I_(13/2) transition are 60.6 s~(-1), 16.3%, and 1.13*10~(-20) cm~2, respectively.The results indicate that this kind of tellurite glass is a promising matrix for 2.7 mum laser.
