The application of organic materials in optical limiting
-
摘要: 对光限制器件的特性进行了简单的评述,并对由自散焦过程产生光限制的机理进行了分析.采用z-扫描方法对有机材料分散红一的非线性折射过程和光限制特性进行了实验研究.对其结果进行了分析讨论,这种分析对于以自作用效应产生最佳光限制效应是十分有用的.Abstract: We simply review the nonlinear optical process in organic materials which can be utilized in passive limiting devices.The mechanism of optical limiting for a self-defocusing processis examined.We experimentally investigate the nonlinear optical refraction and optical limiting characteristics of organic material,and the results are discussed.The analysis is useful in optimizing optical limiting behavior of devices based on self-action.
