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。
This paper reports the second-order nonlinear optical properties of 7-hydroxyquinoline (7HQ) by using superwell Ray scattering (HRS) technique. The laser light with a wavelength of 10 6 4 nm and a pulse width of 35 ps was used as the excitation light to observe the relationship between the super scattered light intensity and incident light intensity. The first hyperpolarization rate of 7HQ was 3.2 × 10 -2 9esu.
