QUE SIGNIFIE LASER EN ANGLAIS

Laser

Laser

Un laser est un dispositif qui émet de la lumière grâce à un processus d'amplification optique basé sur l'émission stimulée de rayonnement électromagnétique. Le terme «laser» est issu d'un acronyme pour «amplification de la lumière par émission stimulée de rayonnement». Un laser diffère d'autres sources de lumière car il émet de la lumière de manière cohérente. La cohérence spatiale permet à un laser d'être focalisé sur un point serré, ce qui permet des applications telles que la découpe au laser et la lithographie. La cohérence spatiale permet également à un faisceau laser de rester étroit sur de longues distances, permettant des applications telles que des pointeurs laser. Les lasers peuvent également avoir une cohérence temporelle élevée qui leur permet d'avoir un spectre très étroit, c'est-à-dire qu'ils n'émettent qu'une seule couleur de lumière. La cohérence temporelle peut être utilisée pour produire des impulsions de lumière - aussi courtes qu'une femtoseconde. Les lasers ont de nombreuses applications importantes. Ils sont utilisés dans des appareils de consommation courante tels que les lecteurs de disques optiques, les imprimantes laser et les scanners à code à barres. Ils sont utilisés en médecine pour la chirurgie au laser et divers traitements de la peau, et dans l'industrie pour la coupe et le soudage des matériaux. Ils sont utilisés dans les dispositifs militaires et d'application de la loi pour marquer les cibles et la portée et la vitesse de mesure.

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". A laser differs from other sources of light because it emits light coherently. Spatial coherence allows a laser to be focused to a tight spot, enabling applications like laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over long distances, enabling applications such as laser pointers. Lasers can also have high temporal coherence which allows them to have a very narrow spectrum, i.e., they only emit a single color of light. Temporal coherence can be used to produce pulses of light—as short as a femtosecond. Lasers have many important applications. They are used in common consumer devices such as Optical disk drives, laser printers, and barcode scanners. They are used in medicine for laser surgery and various skin treatments, and in industry for cutting and welding materials. They are used in military and law enforcement devices for marking targets and measuring range and speed.

définition de laser dans le dictionnaire anglais

La première définition du laser dans le dictionnaire est une source de rayonnement optique, infrarouge ou ultraviolet de haute intensité produite à la suite d'une émission stimulée maintenue dans un milieu solide, liquide ou gazeux. Les photons impliqués dans le processus d'émission ont tous la même énergie et la même phase de sorte que le faisceau laser est monochromatique et cohérent, ce qui lui permet d'être mis au point. Une autre définition de laser est une source similaire produisant un faisceau de n'importe quel rayonnement électromagnétique, tel qu'un rayonnement infrarouge ou micro-ondes. Le laser doit également utiliser un laser, en particulier dans le cadre d'un traitement médical.
