Web6. I complete Gerard's answer: up-conversion is the reverse process, where two low frequency photons are converted to a single high-frequency photon. So basically down- and up-conversion correspond to a frequency conversion of the photons through a nonlinear interaction.

WebSep 17, 2009 · Down-converted photons are produced in pairs, yielding strong intensity correlations among the twin beams. To produce twin photons, a pump photon must be annihilated; thus, anticorrelations are expected between the reflected pump intensity and the sum of twin beams’ intensities. The frequency constraint translates into a constraint for …
