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
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
parametric conversion — parametric conversion, a process for changing a beam of light of one frequency into two beams of different frequencies: »the parametric conversion of X rays … Useful english dictionary
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
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

Potassium titanyl phosphate — (KTiOPO4) or KTP is a nonlinear optical material which is commonly used for frequency doubling diode pumped solid state lasers such as and other neodymium doped lasers. The material has a relatively high optical damage threshold ( 15 J/cm²), a… … Wikipedia
Modelocking — Mode locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10 12s) or femtoseconds (10 15s).The basis of the technique is to induce a fixed phase… … Wikipedia
Mode-locking — is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10−12 s) or femtoseconds (10−15 s). The basis of the technique is to induce a fixed phase… … Wikipedia
