These techniques include Raman scattering, in which light returns with a shift in wavelength as a result of atomic or molecular laser excitation.

这项技术包含拉曼散射，这种散射指反射光会因为原子或分子的激发而有一个波长上的移动。

Stimulated Raman Scattering is one of the methods to shift the UV excimer laser radiation into the specific wavelengths in the near UV and visible regions.

受激喇曼散射可以将紫外准分子激光辐射频移到特定的近紫外和可见光波长。
