• 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 ring-down spectroscopy — (CRDS) is a spectroscopic technique for measuring the transmission or more accurately, the absorbance of light through a material. CRDS can provide extremely sensitive measurements, allowing scientists to measure very small differences in the… …   Wikipedia

• Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… …   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

• Optical levitation — A force diagram showing how vertical and lateral stabilization occurs in a vertically oriented optical trap. Optical levitation is a method developed by Arthur Ashkin whereby a material is levitated against the downward force of gravity by an… …   Wikipedia

• Cavity quantum electrodynamics — (cavity QED) is the study of the interaction between light confined in a reflective cavity and atoms or other particles, under conditions where the quantum nature of light photons is significant. It could in principle be used to construct a… …   Wikipedia

• Optical decay — is process of relaxation of excitation of an excited quantum system, usually due to the spontaneous emission of a photon or a phonon. Optical decay is dominant mechanism of quenching of excitation of active optical media. In solid state lasers… …   Wikipedia

• Optical downconverter — (ODC) is an example of a non linear optical process, in which two beams of light of different frequencies ω1 and ω2 interact, creating microwave with frequency ω3 = ω1 − ω2. It is a generalization of microwave. In the latter, ω1 = ω2, both of… …   Wikipedia

• Optical physics — Optical physics, or optical science, is a subfield of atomic, molecular, and optical physics. It is the study of the generation of electromagnetic radiation, the properties of that radiation, and the interaction of that radiation with matter,… …   Wikipedia
