It has become easier to study and use with the development of powerful monochromatic lasers.
It is used to monitor pollutants in the ozone and there are hopes that it may be able to identify minerals on Mars. It has become easier to study and use with the development of powerful monochromatic lasers. First predicted by Adolf Smekal in 1923, the spectral analysis of it shows Stokes and anti-stokes lines. It occurs when interactions cause photons to change their wavelength giving them a different frequency from their radiation source. FTP identify this type of inelastic scattering named for an Indian physicist.
