Optical cavity — An optical cavity or optical resonator is an arrangement of mirrors that forms a standing wave cavity resonator for light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser… … Wikipedia
Cavity-Enhanced-Absorption-Spektroskopie — Die Cavity Enhanced Absorption Spektroskopie (CEAS) gehört, wie die Cavity ring down Spektroskopie (CRDS), zu den Methoden der Spektroskopie mittels optischer Resonatoren. Üblicherweise wird nur der englische Begriff benutzt, er lässt sich… … Deutsch Wikipedia
Resonator — A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonance frequencies, with greater amplitude than at others. Although its usage has broadened, the… … 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
Optical microcavity — An optical microcavity is a structure formed by reflecting faces on the two sides of a spacer layer or optical medium. The name microcavity stems from the fact that it is often only a few micrometers thick, the spacer layer sometimes even in the… … Wikipedia
Cavity — A cavity is a hole. It may refer to: *Dental cavity, damage to the structure of teeth *Resonator, a device designed to select for waves of particular wavelengths ** Optical cavity, the cavity resonator of a laser *Cavitation, the phenomenon of… … Wikipedia
Vertical-cavity surface-emitting laser — The vertical cavity surface emitting laser (VCSEL; [v ɪxl] ) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge emitting semiconductor lasers (also in plane lasers)… … Wikipedia
Electromagnetic cavity — An electromagnetic cavity is a cavity that acts as a container for electromagnetic fields such as photons, in effect containing their wave function inside. The size of the cavity determines the maximum photon wave length that can be trapped.… … Wikipedia
