Laser and Its Application in Industry.

      Аннотация: The word laser is made from the first letters of the phrase light amplification by the inductive emission of radiation in Latin, which is usually in the near infrared, visible and ultraviolet wavelengths of the electromagnetic spectrum. Laser-like emissions of longer wavelengths in the microwave region are called "masers". Basically, laser is called a coherent and monochromatic light source. The proposal of using inductive emission from a system with inverse population for microwave amplification was independently given by weber, Gordon, Zeiger, Townes, Basov and Prokhorov. The first practical use of such boosters was done by the group of Jordon, Zeiger and Townes at the University of California. This group chose the name Mizer, which was formed from the beginning of the letters Microwave Amplification by Stimulated Emission of Radiation. The first maser was made using microwave transition in ammonia molecules. In 1958, the first suggestion of maser activity at light frequencies was made in an article by Scavolo and Townes. In 1960, less than two years later, Millman succeeded in making a pulsed ruby laser.
