stimulated Raman scattering

Stimulated Raman scattering is a nonlinear optical process where intense light interacts with a material, causing molecules to vibrate at specific frequencies. When incident light of a certain wavelength passes through, some photons are scattered, losing energy to excite molecular vibrations. This results in new light waves with different wavelengths: the scattered light is shifted slightly from the original, in a process called Raman shift. This phenomenon enables detailed analysis of materials’ molecular structures and is used in applications like spectroscopy and laser technology to identify chemical compositions and generate new wavelengths of light.
