The Wonderful World of Lasers
Laser stands for Light Amplification by the Stimulated Emission of Radiation. Lasers work by creating an strong beam of dazzling light that travels in a single direction. The laser gets the unique capability to produce one specific color or wavelength of light, that can be varied in its intensity and pulse period. The most recent laser systems have grown to be remarkably precise and selective, permitting treatment effects and safety levels not previously obtainable. All lasers have an energized substance that can raise the strength of light that passes through it. This substance is named the amplifying method and it's rather a solid, a liquid or a gas.
Einstein can be considered as the daddy of the laser. 80 years back he postulated photons and stimulated emission and earned the Nobel Prize for related exploration on the photoelectric result. This section discusses the historical development from microwave lasers to optical lasers and finally to x-ray lasers and lasers uncovered in space. Some theorists were on the right course, especially Planck, who proposed that nature acted through the use of quanta of energy. Nonetheless it was the young, unfamiliar Albert Einstein who described everything and started the discipline of quantum mechanics along with his paper on the photoelectric effect. Einstein demonstrated that light will not consist of continuous waves, nor of little, hard particles. Rather, it is present as bundles of wave energy known as photons. Each photon comes with an energy that corresponds to the regularity of the waves in the bundle. The bigger the regularity (the bluer the colour), the higher the energy carried by that bundle.
