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
Spectral bands — are part of optical spectra of polyatomic systems, including condensed materials, large molecules etc. Each line corresponding to one level in atom splits in molecules. When the number of atoms is large, one gets continuum of energy levels, so… … Wikipedia
Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… … Wikipedia
Optical interferometry — combines two or more light waves in an optical instrument in such a way that interference occurs between them. Early interferometers used white light sources and also monochromatic light from atomic sources (e.g., Young s double slit experiment… … Wikipedia
