用热极化方法研究了60GeS(2)-20Ga(2)S(3)-20KBr型硫卤化物玻璃的二次谐波产生。通过Maker条纹分析，在极化样品中获得了高达7.0 pm/V的大的二阶非线性极化率。我们相信这是第一次在含有大量碱性离子的硫卤化物玻璃中观察到明显的二次谐波(6.25at.%)。这种观测在所有光波导器件中都有很大的潜在用途。
Second-harmonic generation in 60GeS(2)-20Ga(2)S(3)-20KBr chalcohalide glass was investigated by the thermal poling method. A large second-order nonlinear susceptibility, as high as 7.0 pm/V, was obtained in a poled sample by Maker fringe analysis. We believe this to be the first time that a clear second-harmonic wave was observed in chalcohalide glasses containing large amount of alkali ions (6.25 at. %). Such observation is of great potential use in all optical waveguide devices.
