当光通过介质时，由于光的散射可以观察到光的频率发生变化，位相也发生无规则变化的现象。这种现象称为喇曼效应或喇曼散射。研究散射过程需要采用与荧光现象截然不同的模型来处理。
利用银镜作为衬底，本文对乳酸钙的表面增强喇曼散射效应进行了研究。
The Surface Enhanced Raman Scattering (SERS) effect from Calcium lactate (CL)on Ag mirror is studied in this paper.
本文描述了激光束功率限幅器的被动技术。这一技术是基于后向喇曼的饱和效应。
We describe a completely passive technique based on backward Raman sato ration effect for the power of light beams.
考虑受激喇曼散射的竞争效应，求得了简并四波混频后向波参量振荡信号强度与泵浦输入强度的关系。
