Multiple-prism dispersion theory — The first description of multiple prism arrays, and multiple prism dispersion, was given by Newton in his book Opticks.[1] Prism pair expanders were introduced by Brewster in 1813.[2] A modern mathematical description of the single prism… … Wikipedia
Multiple-prism grating laser oscillator — Multiple prism grating laser oscillators,[1] or MPG laser oscillators, use multiple prism beam expansion to illuminate a diffraction grating mounted either in Littrow configuration or grazing incidence configuration. Originally, these narrow… … Wikipedia
Fiber Bragg grating — A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the… … Wikipedia
Diffraction grating — A very large reflecting diffraction grating. In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. The directions of these beams … Wikipedia
Long-period fiber grating — A long period fiber grating is an optical fiber structure with the properties periodically varying along the fiber, such that the conditions for the interaction of several copropagating modes are satisfied. The period of such a structure is of… … Wikipedia
normal dispersion — noun : dispersion (as of light by an optical grating) in which the separation of components in any one spectrum increases continuously and almost uniformly with the wavelength, the separation being a monotonic function of the dispersion variable … Useful english dictionary
angular dispersion — Optics. a measure of the angular separation of light rays of different wavelength or color traversing a prism or diffraction grating, equal to the rate of change of the angle of deviation with respect to the change in wavelength. * * * … Universalium

GRENOUILLE — Grating eliminated no nonsense observation of ultrafast incident laser light e fields (GRENOUILLE) is an ultrashort pulse measurement technique based on frequency resolved optical gating (FROG). The somewhat frivolous acronym was chosen because… … Wikipedia
Chirped pulse amplification — Diagramatic scheme of chirped pulse amplification. Chirped pulse amplification (CPA) is a technique for amplifying an ultrashort laser pulse up to the petawatt level with the laser pulse being stretched out temporally and spectrally prior to… … Wikipedia
Monochromator — in a x ray beamline at the Advanced Photon Source, Argonne National Laboratory. A monochromator is an optical device that transmits a mechanically selectable narrow band of wavelengths of light or other radiation chosen from a wider range of… … Wikipedia
