本文首次报道了对采用溶胶凝胶和原位生长工艺制备的Ｃｄ_ｘＨｇ_(１－ｘ)Ｔｅ／ＳｉＯ_２固溶体微品掺杂玻璃进行的三阶非线性光学性质实验研究及其结果。利用回返式简并四波混频技术，测得该固溶体掺杂玻璃的三阶非线性极化率的值为１０￣（－１２）ｅｓｕ量级。此结果比纯ＳｉＯ_２基体提高了２个数量级。表明该固溶体掺杂玻璃三阶非线性明显增强，在同样条件下，测得ＣＳ_２的三阶非线性极化率ｘ（３）为（１．７±０．２）×１０￣(－１２)ｅｓｕ，与国际上报道完全一致。
This paper reports for the first time the third-order nonlinear optical properties of Cd_xHg_ (1-x) Te / SiO_2 solid solution doped glass prepared by sol-gel and in-situ growth and its results. The third-order nonlinear polarizability of the solid solution doped glass was measured by the regression degenerate four-wave mixing technique with the magnitude of 10 ~ (-12) esu. This result is two orders of magnitude higher than pure SiO 2 matrix. It shows that the third order nonlinearity of the solid solution doped glass is obviously enhanced. Under the same conditions, the third order nonlinear susceptibility x (3) of CS_2 is (1.7 ± 0.2) × 10 ~ (-12) esu, exactly the same as reported in the world.
