A laser is a maser which operates at optical frequencies. It is a device which produces an intense beam of visible or infrared coherent light by pumping atoms to ever higher energy levels and allowing them to oscillate in an optical resonator until the energy level is high enough that a constant stream of photons is emitted. 4, record 1, English, - laser

Some prefer the term "optical maser, "in which the letter "m" stands for "molecular" instead of its originally assigned denotation of "microwave. "While this viewpoint is logical,... the word "laser"... has the virtue of brevity and has won popular acceptance. 2, record 1, English, - laser

An instrument combining a pulsed laser transmitter and optical receiver(usually a telescope) with an electronic signal processing unit used for the detection and ranging of various distant targets in the atmosphere, analogous to the principles of operation of microwave radar. 6, record 2, English, - lidar
Record number: 2, Textual support number: 1 CONT
The lidar technique operates on the same principle as radar; in fact, it is sometimes called laser radar. The principal difference between lidar and radar is the wavelength of the radiation used. Radar uses wavelengths in the radio band whereas lidar uses light, that is usually generated by lasers in modern lidar systems. 7, record 2, English, - lidar
Record number: 2, Textual support number: 2 CONT
There are three basic generic types of lidar: range finders, DIAL, and Doppler lidars. Rande finder lidars are the simplest lidars. They are used to measure the distance from the lidar instrument to a solid or hard target Differential Absorption Lidar (DIAL) is used to measure chemical concentrations (such as ozone, water vapor, pollutants) in the atmosphere. Doppler lidar is used to measure the velocity of a target High-resolution DEMs with vertical accuracy as good as 10 cm can be created with Lidar. Lidar is also better able to map bare earth elevations in forested or vegetated areas than other methods because only a single laser pulse needs to be able to reach between trees and the ground. 8, record 2, English, - lidar

En avril 1997 PHARAO a été soumis à l'Agence spatiale européenne (ESA) dans le cadre d'une mission plus large appelée ACES (Atomic Clock Ensemble in Space). Son principe est de mettre à bord de la Station spatiale internationale (ISS) un ensemble comprenant des horloges ultra-stables et des méthodes de transfert temps/fréquences performantes. Dans la configuration de base de ACES, les deux horloges retenues sont PHARAO et un maser à hydrogène fourni par l'Observatoire de Neuchâtel (Suisse). Le transfert de temps est réalisé par un lien optique utilisant des impulsions laser très brèves (T2L2, fourni par l'Observatoire de la Côte d'Azur) et également par un lien dans le domaine micro-onde qui, lui, peut fonctionner par toutes conditions atmosphériques.

Le TESF (transport d'énergie sans fil) [...] suppose trois opérations relativement simples : la conversion de l'électricité en ondes, la transmission de ces ondes et enfin leur reconversion en électricité après réception [...] Pour faire voyager l'électricité, il vaut mieux utiliser des micro-ondes, qui ont une longueur plus importante (environ 12 centimètres) et qui sont pratiquement insensibles aux perturbations atmosphériques. Dans le cas du transport d'énergie sans fil (TESF), l'électricité est transformée en un rayon de micro-ondes, similaire au rayon laser [...] mais invisible. Le faisceau est dirigé vers une antenne de réception, composée de milliers de radiopiles. [On peut] produire de l'électricité à partir des micro-ondes en redressant les courants produits dans une antenne avec une diode à haute fréquence, qui nous donne du courant continu. L'élément combinant une antenne haute fréquence et le composant redresseur s'appelle une radiopile. Chaque radiopile ne produit qu'un peu d'électricité, mais en en associant des dizaines, des milliers, des millions, on obtient à la sortie le nombre de gigawatts demandés. 4, record 10, French, - transport%20d%27%C3%A9nergie%20sans%20fil

The laser(or lidar) velocimeter [lidar=light radar] operates in a fashion entirely analogous to that of the airborne Doppler weather radars likely soon to be available for detecting turbulence in storm cells. As with radars, the device detects air movements by observing the motion of particles suspended in the air and carried with it. The only significant difference is that a beam of coherent infrared radiation is used to scan ahead of the aircraft, instead of a beam(or series of pulses) of radio energy in the considerably longer-wavelength microwave band. The frequency of the back-scattered echoes or reflections undergoes Doppler shift detection by standard heterodyning techniques, which involve comparing the frequency of the reflected illumination with that of the original laser beam. Any reflecting object or material which has motion relative to the transmitter/receiver will cause a detectable shift in frequency, which can be isolated from the transmitter's own proper motion(over the ground) and thus yield a precise indication of the speed at which the air is moving several hundred metres in front of the aircraft. From this data, it is easy to compute what the air speed of the aircraft will be when it reaches that particular patch of air in a few seconds’ time [and hence detect possible turbulence ahead]. 2, record 11, English, - laser%20velocimeter
