论文摘要
这项工作描述了基于咪唑的离子液体和相应的热光学参数的非线性光学特性的实验和理论研究。非线性光学特性的实验结果，例如非线性折射率和热光学特性，由Z-SCAN和EZ-SCAN技术和飞秒激光源确定。通过极化性，超极化性的一阶和二阶，讨论了通过密度函数理论（DFT）进行的线性和非线性光学特性的理论模拟。提出了理论和实验结果之间的相关性，其中可以将每个离子液体的信号与非线性光学特性进行比较。
This work describes the experimental and theoretical study of the nonlinear optical properties of the imidazolium cation based ionic liquids and the corresponding thermo-optical parameters. Experimental results of nonlinear optical properties, such as nonlinear refractive index and thermo-optical properties are determined by Z-scan and EZ-scan techniques with a femtosecond laser source. Theoretical simulations of linear and nonlinear optical properties performed by density functional theory (DFT) are discussed, in terms of polarizability, the first and second-order of hyperpolarizability. A correlation between the theoretical and experimental results is presented, where the variation of the signals of each ionic liquid can be compared with their nonlinear optical properties.
