LIGHT AMPLIFICATION BY STIMULATED EMISSION OF RADIATION
Introduction
The rays produced by these gadgets can be used in different ways by a human because it provides benefits to humans. The limited range of visible light is covered by it.
History
In 1917, the first explanation was given by Albert Einstein.– In 1960, the first laser device was made by Theodore H. Maiman. To make the invention possible the theories of Charles Hard Townes and Arthur Leonard Schawlow help.
Principles
The principles that are used by the equipment helps in understanding the process of working on a laser device. The rules of Quantum Mechanics are followed by the laser.
Elements
The three elements of laser are to be used by the laser work. The three elements are Lasing material or active medium, external energy source, and optical resonator.
Characteristics
The beam of light is narrow as compared to the other devices. The distance between the two walls on which deviation is dependent. The beam is suffering from the extent of diffraction.
Applications
The application of lasers is used to transmit and process information.The application of the laser is used to deliver a precise amount of energy.
Types
The importance of lasers is recognized by the people. It also encourages them by providing different types of laser. Types of laser are Solid State LASER, Dye or Liquid LASER and many more.
