Beschreibung
The Laser, a fascinating new light source with numerous applications in our daily life was first realized some 50 years ago. Though the principle was initiated in 1916 when Einstein introduced a new concept radiation matter-interaction known today as stimulated emission of electromagnetic radiation. Laser is the acronym of Light Amplification By Stimulated Emission Of Radiation. It is the brightest monochromatic (single color) light existing today. It is produced by an electro optical device that emits organized light (rather than the random-pattern light emitted from a light bulb) in a very narrow, intense beam by a process of optical feedback and amplification.
