Parametric equation — butterfly curve. In mathematics, parametric equations are a method of defining a curve. A simple kinematical example is when one uses a time parameter to determine the position, velocity, and other information about a body in motion.Abstractly, a … Wikipedia
Parametric oscillator — A parametric oscillator is a simple harmonic oscillator whose parameters (its resonance frequency omega and damping eta) vary in time in a defined wayAnother intuitive way of understanding a parametric oscillator is as follows: a parametric… … Wikipedia
Optical parametric oscillator — Infrared optical parametric oscillator An optical parametric oscillator (OPO) is a parametric oscillator which oscillates at optical frequencies. It converts an input laser wave (called pump ) into two output waves of lower frequency (ωs,ωi) by… … Wikipedia
Spontaneous parametric down-conversion — (SPDC) is an important process in quantum optics. A nonlinear crystal splits incoming photons into pairs of photons of lower energy whose combined energy and momentum are equal to the energy and momentum of the original photon. The state of the… … Wikipedia
Nonlinear optics — (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the dielectric polarization P responds nonlinearly to the electric field E of the light. This nonlinearity is typically only observed… … Wikipedia
Oscillateur parametrique optique — Oscillateur paramétrique optique Un Oscillateur paramétrique optique (OPO) est une source de lumière cohérente et monochromatique. À partir d une onde laser de pompe de fréquence ωp, un OPO produit deux ondes de fréquences inférieures : le… … Wikipédia en Français
Oscillateur paramétrique optique — Un oscillateur paramétrique optique (OPO) est une source de lumière cohérente et monochromatique. À partir d une onde laser de pompe de fréquence ωp, un OPO produit deux ondes de fréquences inférieures : le signal à ωs et le complémentaire à … Wikipédia en Français
