Optical parametric oscillation (OPO), era of a signal and idler wave using a parametric amplifier in a resonator (with no signal enter). Optical parametric technology (OPG), like parametric oscillation however with out a resonator, using a very high acquire instead. Spontaneous parametric down-conversion (SPDC), the amplification of the vacuum fluctuations in the low-achieve regime. Optical rectification (OR), era of quasi-static electric fields. Nonlinear gentle-matter interplay with free elect...
