摘要

本研究成功地采用熔融淬火技术制备了成分为x SiO2-(80-x) Bi2O3-15 B2O3-5TeO2 (x = 0,5,10和15)的季系硼硅碲酸盐玻璃体系。制备的玻璃样品的线性折射率(n0)随SiO2含量的增加而减小。三阶非线性光学性质,即非线性折射率(n2)和非线性吸收系数(β),已通过理论模型拟合实验观察到的闭孔和开孔z扫描测量值,并发现依赖于所研究的玻璃成分中硅酸盐含量的量。还计算了包含实部和虚部的三阶非线性磁化率(χ(3))。

Non-linear optical properties of SiO2 modified Bi2O3-TeO2-B2O3 glass system
In present study, quaternary bismuth borosilicate tellurite glass system with compositions x SiO2-(80-x) Bi2O3-15 B2O3-5TeO2 (x = 0, 5, 10 and 15) has been successfully prepared by melt-quenching technique. The linear refractive index (n0) of prepared glass samples has been observed to decrease with increase in SiO2 content. Third order nonlinear optical properties viz. nonlinear refractive index (n2) and nonlinear absorption coefficient (β) have been estimated by fitting of experimentally observed closed and open aperture Z-scan measurements with theoretical models and found to be dependent on amount of silicate content in studied glass compositions. The third order nonlinear susceptibility (χ(3)) including real and imaginary parts have also been calculated.
