What is Laser and how it works...?
A LASER is an acronym which means light amplification by stimulated emission of radiation . so we can say laser is nothing but a device that emits light through optical amplification process which is based on stimulated emission of electromagnetic radiation.
Basically lasers are devices which produce intense beams of light which are coherent,monochromatic and highly collimated .
lasers have extremely pure(monochromatic) wavelength compared with other source of lights. all of the photons (energy) that
make up the laser beam have a fixed phase relationship (coherence)
with respect to one another.laser light has very low divergence so it travel over great distance or can be focused to a very small tight spot with very high brightness power.because of all these properties lasers are used in variety of applications in day today life.
Working of lasers is based on quantum physics when atom stuck by light waves begin to vibrate and it will cause electrons to jump to higher level until the atoms reach an excited state. when atom begin to relax, their energy is released in the form of photons, which are simply pockets of light energy.
