| 摘 要： | 为测定粉末材料的紫外波段二阶非线性光学特性,根据Kurtz-Perry粉末倍频效应理论,开展了紫外粉末二阶非线性光学性能测试的研究。测试光源为氙灯泵浦的Nd∶YAG-KTP电光调Q激光器,KTP为二倍频晶体,输出波长532 nm,单脉冲能量100 mJ,重复频率1~10 Hz,脉冲宽度为8 ns。为保证266 nm光的透过率,采用紫外融石英做窗口片,型号为JGS1;为保证测试的准确性,选择光栅光谱仪分光。经紫外常用的KDP、LBO、BBO等测试,证明本方法具有稳定可靠、判别精度高、操作简单等优点,可以有效地定性或半定量测试材料的紫外二阶非线性光学性能,为研究紫外二阶非线性光学材料提供了一种重要的测试手段。

| Abstract: | In order to determine the second-order nonlinear optical property of the ultraviolet powder material,according to the Kurtz-Perry powder second-order nonlinear optical theory,a study on the second-order nonlinear optical performance test of the ultraviolet powder was carried out.The test laser is a Nd∶YAG-KTP electro-optical Q-switched laser pumped by xe-lamp.KTP is the nonlinear optical crystal,with an output wavelength of 532 nm,a single pulse energy of 100 mJ,a repetition frequency of 1-10 Hz,and a pulse width of 8 ns.In order to ensure the transmittance of 266 nm,ultraviolet melting quartz JGS1 was used as the window.In order to ensure the accuracy of the test,the grating spectrometer was selected to split the light.According to tests of KDP,LBO,BBO,which commonly used in UV prove that this method has the advantages of stability,reliability,high discrimination accuracy,and simple operation.As an important testing method,it can effectively qualitatively or semi-quantitatively test the UV second-order nonlinear optical properties of materials. |
