摘要：

采用熔融-淬冷法制备了(100-x)(0.8GeS2-0.2Ga2S3)-xPbCl2 (x = 0，5，10，15，摩尔分数)系列硫卤玻璃，测试了样品的密度、可见-中远红外的透过性以及样品的折射率，并且根据Z扫描测试原理测试了飞秒脉冲下，样品在800 nm波长下的三阶非线性光学特性。结果表明：非线性折射率n2和非线性吸收系数β均随着PbCl2含量的增加而增大，特别是x = 15的样品的非线性折射率n2 = 2.812 × 10-17 m2/W，非线性吸收系数β = 4.298×10-11 m/W，较传统无重金属参杂硫系玻璃的三阶非线性性能明显提高。

A series of (100-x)(0.8GeS2-0.2Ga2S3)-xPbCl2 (x = 0, 5, 10, 15, mole fraction) chalcogenide glasses were prepared by conventional melt-quenching method. The physical and optical properties (densities, refractive indices, absorption spectra and transmission spectra) were determined. The Z-scan technique was carried out to investigate the third-order nonlinear optical properties of the samples at 800 nm. The effect of PbCl2 content on the linear refractive index, transmission property, and third-order nonlinear property of samples was also investigated. The results show that the linear refractive index nonlinear refractive index n2, nonlinear absorption coefficient β and third-order nonlinear optical susceptibility of samples increases with PbCl2 content. The values of n2 and β with the content of 15% PbCl2 are equal to n2=2.812×10-17 m2/W and β = 4.298 × 10-11 m/W, respectively, which is much better than the chalcogenide glass without the heavy metal doped.
