resonant laser
1Laser absorption spectrometry — (LAS) refers to techniques that utilize lasers to assess the concentration or amount of a species in gas phase by absorption spectrometry (AS).It is well known that optical spectroscopic techniques in general and laser based techniques in… …
2Laser cooling — refers to the number of techniques in which atomic and molecular samples are cooled through the interaction with one or more laser light fields. The first example of laser cooling, and also still the most common method of laser cooling (so much… …
3laser — /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; …
4Resonant tunnelling diode — A resonant tunnel diode (RTD) is a device which uses quantum effects to produce negative differential resistance (NDR). As an RTD is capable of generating a terahertz wave at room temperature, it can be used in ultra high speed circuitry.… …
5Laser — For other uses, see Laser (disambiguation). United States Air Force laser experiment …
6Laser 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 …
7Laser pointer — A laser pointer is a portable, pen sized laser designed to be held in the hand, and most commonly used to project a point of light to highlight items of interest during a presentation. Most laser pointers have low enough power that the projected… …
8Resonant-cavity light emitting diode — Die „resonant cavity light emitting diode“ (RCLED oder RC LED, dt. »Leuchtdiode mit optischen Resonator«) ist eine Form von Leuchtdioden. Funktionsweise Das Wirkprinzip funktioniert ähnlich einem VCSEL (Vertical Cavity Surface Emitting Laser),… …
9Laser-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… …
10resonant-cavity light emitting diode — Die „resonant cavity light emitting diode“ (RCLED oder RC LED, dt. »Leuchtdiode mit optischem Resonator«) ist eine Form von Leuchtdioden. Funktionsweise Das Wirkprinzip funktioniert ähnlich einem VCSEL (Vertical Cavity Surface Emitting… …
