Preferred Label : non-linear optical techniques;
IUPAC acronym : CARS;
IUPAC definition : Collective name applied to techniques related to non-linear optical effects.;
Scope note : low order non-linear techniques, such as three-wave mixing, are related to the second
order polarization. for a random isotropic medium with inversion symmetry, the second-order
polarization vanishes and then the lowest order optical non-linear techniques, as
well as the higher order non-linear techniques are related to the third-order polarization
and the corresponding hyper-susceptibility.; some of these spectroscopies are four-wave mixing, hole burning, photon echoes, time-resolved
coherent anti-stokes raman (cars), transient grating and stimulated pumping. these
techniques differ in the nature of the pulse sequence, the geometry and the choice
of a spatial direction (phase matching), as well as the mode of detection.;
