What is Optical parametric amplifier?

An electro-optical targeting system , is a system employed to track and locate targets in aerial warfare. It can use charge-coupled device TV cameras, laser rangefinders and laser designators.

An optical train, also called an optical assembly, is an arrangement of optical components to guide a line of sight and/or a laser beam. For example, the position and angle...

An acousto-optical spectrometer is based on the diffraction of light by ultrasonic waves. A piezoelectric transducer, driven by the RF signal , generates an acoustic wave in a crystal. This...

In the field of photonics, optical chaos is chaos generated by laser instabilities using different schemes in semiconductor and fiber lasers. Optical chaos is observed in many non-linear optical systems....

Optical cross section is a value which describes the maximum amount of optical flux reflected back to the source. The standard unit of measurement is m/sr. OCS is dependent on...

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...

Optical lift is an optical analogue of aerodynamic lift, in which a cambered refractive object with differently shaped top and bottom surfaces experiences a stable transverse lift force when placed...

A multivariate optical element , is the key part of a multivariate optical computer; an alternative to conventional spectrometry for the chemical analysis of materials. It is helpful to understand...
