LASER is a mechanism by which electromagnetic radiations are emitted, characteristically light or visible light by the method of stimulated emission. Light amplification by stimulated emission of radiation is known as LASER. The laser light which is emitted in this process is spatially consistent, very fine beams of a low-divergent capacity that can be controlled over with the use of lenses. When we consider laser technology, the term coherent light signifies a light source that discharges light of synchronized waves of indistinguishable frequency and phase. The laser beam of consistent light makes a distinction from the sources of light that gives out rambling light beams, of unsystematic and uneven phase changeable with time and position of the object or the source. Laser light beams are in general have a very narrow-wavelength electromagnetic field monochromatic beam. However it is observer that there are a few types of laser beams that emits a broad spectrum of light beams and gives out beams with different wavelengths at the same time.

What do call as the gain medium of a laser? It is nothing but a substance of expedient purity, mass, concentration, and contour that intensifies the beam through the method of stimulated emission. The gain medium of laser can be of any stage like liquid, solid or even plasma. This gain medium normally attracts pump energy that heaves a few electrons into higher-energy level, exited or the so called quantum state. Units can work together with light both the ways by attracting photons inside them or by discharge of photons. The emission process that occurs at this stage might be a spontaneous one or stimulated. The photon is discharged in the similar direction of the light that passes by. The state of population inversion is attained and the quantity of stirred discharge owing to light that passes all the way through is larger than the quantity of assimilation, when the number of units in one excited state goes beyond the numeral of particles in the lower-energy state for that reason, the light is augmented. When an optical amplifier is positioned within a resonant laser is achieved.

LASER is used everywhere these days and its used are wide. Starting from medical purposes to industrial purposes, the cutting quality of laser beam is known. Laser cutting is mainly used in industries for its perfect finish. Laser cutting is a well-known and widely used expertise that makes use of the cutting quality of the laser beams to cut materials. Laser cutting is normally done in the field of industrial manufacturing applications and tools. Laser cutting works by throwing the yield of a high power laser, by workstation, at the surface of the object to be cut. Its observed that the surface of the material melts, burns, vaporizes away or sometimes blown away by a spurt of gas that departs from a rim with a high class surface finish. Industrial laser cutters are mainly used widely to cut out the flat-sheet materials or piping.
