Preferred Label : downconversion;
IUPAC definition : Process by which a photon with frequency ν1 interacts with a non-linear medium and
splits into two simultaneously emitted photons with frequencies ν2 and ν3 so that
the energy is conserved: \[\nu _{1} \nu _{2} \nu _{3}\];
Scope note : the efficiency of the conversion process depends on the parametric gain in the non-linear
material. this in turn depends on the power of the incident radiation, the photon
frequencies, their indices of refraction in the material, and the non-linear hyper-susceptibility
of the material.; also known as a parametric downconversion.;
