Conclusion Le mot laser est un acronyme pour "light amplification by stimulated emission of radiation". Les lasers sont des mecanismes qui amplifie la lumiere et produit un faisceau de lumiere consistent qui peut range de infra-rouge a ultraviolet. Il existe plusieurs types de lasers: optique, etat solide, gaz, semi-conducteur, liquide, electron libre et plusieurs autres. Il existe seulement une restriction sur le laser, et celle-ci est l'humain Nous avons pas encore trouve tout ce que le laser peut faire, par contre, les lasers ont deja revolutionne plusieurs champs dans la recherche de la science, manufacture, communication, photographie, medecine et applications militaire. Dans ce rapport, nous allons examine les differents types de laser ainsi que leurs applications en detail. Pour chaque variation de laser nous allons decouvrir plus profondement son inventeur..
Holograms are made by exposing laser light to a piece of film. There is less waste by-products when using lasers because it vaporizes the material. Lasers can easily vaporize surface tumors. The procedure takes about five to ten minutes per eye depending upon how bad the eyesight of the person is. Military The military's main use for lasers is for their missile guidance systems. Warehouses where plastic, cardboard and heavy fabrics are produced use lasers to cut quickly and accurately through the sheets of materials. These lasers can do precision welding. The laser has affected so many different fields of work and most (except for the nuclear warheads) have been positive. Ceci est refroidi par l'air frais qui traverse dans une cavite cylindrique de l'aluminium. This is why I feel that the laser is the greatest advancement in physics. Ce laser fonctionne lorsque les gaz chauds augmentent par les jets correspondamment formes d'une haute pression, une haute chambre de temperature dans une chambre de pression basse. They have already started the construction of satellites that will be able to do this job from space. Doctors are always finding new ways that lasers can be used to make procedures easier to perform and to shorten the length of the procedure and easier on the patient in terms of recovery time. It has also made it safer for the workers because they can be in a separate room out of the danger. Mining Another area in industry where lasers are used is mining.
