21Oscillateur parametrique optique — Oscillateur paramétrique optique Un Oscillateur paramétrique optique (OPO) est une source de lumière cohérente et monochromatique. À partir d une onde laser de pompe de fréquence ωp, un OPO produit deux ondes de fréquences inférieures : le… …
22Oscillateur paramétrique optique — Un oscillateur paramétrique optique (OPO) est une source de lumière cohérente et monochromatique. À partir d une onde laser de pompe de fréquence ωp, un OPO produit deux ondes de fréquences inférieures : le signal à ωs et le complémentaire à …
23Optical frequency multiplier — An optical frequency multiplier is a nonlinear optical device, in which photons interacting with a nonlinear material are effectively combined to form new photons with greater energy, and thus higher frequency (and shorter wavelength). Two types… …
24Conformational change — See also: Database of Molecular Motions A macromolecule is usually flexible and dynamic. It can change its shape in response to changes in its environment or other factors; each possible shape is called a conformation, and a transition between… …
25Summenfrequenzspektroskopie — Die Summenfrequenzspektroskopie (SFS, englisch sum frequency spectroscopy, auch sum frequency generation spectroscopy, SFGS, vibrational sum frequency spectroscopy, VSFS, oder sum frequency vibrational spectroscopy, SFVS, genannt) ist… …
26GRENOUILLE — 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… …
27Deuterated potassium dihydrogen phosphate — (KD2PO4) or DKDP single crystals are widely used in non linear optics as the second, third and fourth harmonic generators for and lasers. They are also found in electro optical applications as Q switches for , , Alexandrite and Ti sapphire lasers …
28Potassium dideuterium phosphate — Deuterated potassium dihydrogen phosphate (KD2PO4) or DKDP single crystals are widely used in non linear optics as the second, third and fourth harmonic generators for Nd:YAG and Nd:YLF lasers. They are also found in electro optical applications… …
