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

Shpolskii matrix — A Shpolskii (or Shpol skii) matrix is a low temperature host guest system consisting of guest or impurity chromophore embedded in a crystaline matrix. The fluorescence emission spectra and absorption spectra of Shpolskii matrices exhibit narrow… … Wikipedia
Motional narrowing — In physics and chemistry, motional narrowing is a phenomenon where a certain resonant frequency has a smaller linewidth than might be expected, due to motion in an inhomogeneous system.[1] Example: NMR spectroscopy A common example is NMR.[1] In… … Wikipedia
Malmquist bias — For other uses of Malmquist, see Malmquist (disambiguation). The Malmquist bias refers to an effect in observational astronomy which leads to the preferential detection of intrinsically bright objects. It was first popularized in 1922 by Swedish… … Wikipedia

Coronal radiative losses — In astronomy and in astrophysics, for radiative losses of the solar corona, it is meant the energy flux irradiated from the external atmosphere of the Sun (traditionally divided into chromosphere, transition region and corona), and, in particular … Wikipedia
Zero-phonon line and phonon sideband — The zero phonon line and the phonon sideband jointly constitute the line shape of individual light absorbing and emitting molecules (chromophores) embedded into a transparent solid matrix. When the host matrix contains many chromophores, each… … Wikipedia
Doppler imaging — Not to be confused with Doppler ultrasound. Inhomogeneous structures on stellar surfaces, i.e. temperature differences, chemical composition or magnetic fields, create characteristic distortions in the spectral lines due to the Doppler effect.… … Wikipedia
