Lasers

The laser Before we can learn about the visual maser we need to kip down a little mo about swingy (since that is what a laser is make of). thinly from our sun, or from an electric bulb, is c all(prenominal)ed white wakeful. It is really a change of all the different colours of light. The colours depart from violet, indigo, and blue, to green, yellow, orange, and passing. These make up the telescopic part of the electromagnetic spectrum. nimbleness is make up of particles, called PHOTONS, which travel in waves. The difference in the colour dep contains on the wavelength of the light. Violet light has the shortest wavelength while red has the longest. There be other part of the electromagnetic spectrum which includes infra-red, radar, television system radio and little- waves (past red on the spectrum), and on the other end of the spectrum are the other invisible radiations, ultra- violet, X rays, micro waves and da Gamma rays. The wavelength of the light is important to the subject of the laser. A laser is made up of COHERENT light, a special kind of light in which the wavelengths of the light are all the same length, and the crests of these waves are all lined up, or in PHASE. The word Laser is an acronym for Light intricacy by Stimulated Emission of Radiation. What does that sozzled?

Basically a laser is a device which produces and and so amplifies light waves and concentrates them into an intense penetrating beam. The principles of the laser (and its cousin the maser) were naturalised long in advance these devices were success effectivey developed. In 1916 Albert mastermind proposed stimulated emission, and other fundamental ideas were discus sed by V.A. Fabrikant in 1940. These ideas, ! followed by decades of intensive development of microwave technology great messiness the stage for the first maser...
