laser emission line
1laser — /lay zeuhr/, n. Physics. a device that produces a nearly parallel, nearly monochromatic, and coherent beam of light by exciting atoms to a higher energy level and causing them to radiate their energy in phase. Also called optical maser. [1955 60; …
2Laser-induced breakdown spectroscopy — (LIBS) is a type of atomic emission spectroscopy which utilises a highly energetic laser pulse as the excitation source. LIBS can analyse any matter regardless of its physical state, be it solid, liquid or gas. Even slurries, aerosols, gels, and… …
3Laser diode — Top: a packaged laser diode shown with a penny for scale. Bottom: the laser diode chip is removed from the above package and placed on the eye of a needle for scale …
4Laser-Kühlung — Laserkühlung ist ein Verfahren, um einzelne Atome mit Hilfe von Laserlicht stark abzukühlen (z. B. zum Erzeugen von optischen Melassen, einer Vorstufe des Bose Einstein Kondensats). Die Grundidee ist folgende: Die Temperatur eines Gases drückt… …
5Laser printer — HP LaserJet 4200 series printer, installed atop high capacity paper feeder …
6Emission 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 …
7Laser applications — There are many scientific, military, medical and commercial laser applications which have been developed since the invention of the laser in the 1958. The coherency, high monochromaticity, and ability to reach extremely high powers are all… …
8laser-line shift — lazerio spinduliuotės linijos poslinkis statusas T sritis radioelektronika atitikmenys: angl. laser line shift vok. Laserlinienverschiebung, f rus. сдвиг линии генерации лазера, m; смещение линии генерации лазера, n pranc. déplacement de raie d… …
9Stimulated emission — In optics, stimulated emission is the process by which an electron, perturbed by a photon having the correct energy, may drop to a lower energy level resulting in the creation of another photon. The perturbing photon is seemingly unchanged in the …
10Atomic spectral line — In physics, atomic spectral lines are of two types: * An emission line is formed when an electron makes a transition from a particular discrete energy level of an atom, to a lower energy state, emitting a photon of a particular energy and… …
