Gain (lasers) — Gain (or amplification) in laser physics is a process, where the medium transfers part of its energy to the emitted electromagnetic radiation, resulting in an increase in laser power. This is basic principle of all lasers.Quantitatively, the… … Wikipedia
Beer-Lambert law — In optics, the Beer–Lambert law, also known as Beer s law or the Lambert–Beer law or the Beer–Lambert–Bouguer law (in fact, most of the permutations of these three names appear somewhere in literature) is an empirical relationship that relates… … Wikipedia
Magnetic circular dichroism — (MCD) is the differential absorption of left and right circularly polarized (LCP and RCP) light, induced in a sample by a strong magnetic field oriented parallel to the direction of light propagation. MCD measurements can detect transitions which … Wikipedia
Organic solar cell — An organic photovoltaic cell (OPVC) is a photovoltaic cell that uses organic electronics a branch of electronics that deals with conductive organic polymers or small organic molecules[1] for light absorption and charge transport. The plastic… … Wikipedia
Emission spectrum — The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted by the element s atoms or the compound s molecules when they are returned to a lower energy state. Each element s … Wikipedia
Cavity ring-down spectroscopy — (CRDS) is a spectroscopic technique for measuring the transmission or more accurately, the absorbance of light through a material. CRDS can provide extremely sensitive measurements, allowing scientists to measure very small differences in the… … Wikipedia
Optical tweezers — (originally called single beam gradient force trap ) are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force (typically on the order of piconewtons), depending on the refractive index mismatch… … Wikipedia
Ultraviolet–visible spectroscopy — Beckman DU640 UV/Vis spectrophotometer. Ultraviolet visible spectroscopy or ultraviolet visible spectrophotometry (UV Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet visible spectral region. This… … Wikipedia
