超瑞利散射法研究7-羟基喹啉的一阶超极化率

Investigation on First Hyperpolarizability of 7-hydroxyquinoline with Hyper-Rayleigh Scattering Method

本文报道了利用超瑞利散射 (HRS)技术研究 7-羟基喹啉 (7HQ)的二阶非线性光学性质。采用波长为 10 6 4 nm、脉冲宽度为 35 ps的激光作激发光 ,观测其超散射光强与入射光强的关系 ,得到 7HQ的一阶超极化率为 3.2× 10 - 2 9esu。

The second order optical nonlinearity of 7 hydroxyquinoline (7HQ) was investigation by using hyper Rayleigh scattering (HRS) method.The relationship between the HRS intensity and the intensity of incident beam was measured with 35 ps laser pulse at 1064 nm.The first hyperplarizability of 7HQ is 3.2×10 -29 esu.
