摘要：低频拉曼散射是一种由纳米和亚微米颗粒的局部声学振动产生的自发非弹性散射。它是一种获得有关纳米、亚微米颗粒的形状、尺寸分布、它们与电磁辐射相互作用等信息的方法。受激低频拉曼散射是其对应的受激过程，具有转换效率高，光谱窄等特点。在本次报告中，将讲述受激低频拉曼散射的基本原理、性质及其应用。

*Abstract: Low-frequency Raman scattering is a spontaneous, non-elastic scattering produced by the local acoustic vibrations of nano- and sub-micron particles. It is a method to obtain information about the shape, size distribution, and interaction of these particles with electromagnetic radiation. Stimulated low-frequency Raman scattering is the corresponding stimulated process, which has high conversion efficiency and narrow spectral width. In this presentation, the fundamental principles, properties, and applications of stimulated low-frequency Raman scattering will be discussed.

*Profile：Bi Dongxue graduated with a Ph.D. from Bauman Moscow State Technical University in December 2020. She is currently an associate researcher at the Lebedev Physical Institute of the Russian Academy of Sciences and an associate professor at Bauman Moscow State Technical University. Her research focuses on the optical properties and applications of micro- and nanostructures.
