The laser is a device that a beam of light that is both scientifically and practically of great use because it is coherent light. The beam is produced by a process known as stimulated emission, and the word "laser" is an acronym for the phrase "light amplification by stimulated emission of radiation." Light is just like radio waves in the ...

... as a wave. In beams of light whether they are ordinary natural or artificial the photon waves will not be traveling together because they are not being emitted at exactly the same moment but instead at random short bursts. Even if the light is of a single frequency that statement would also be true. A laser is useful because it produces light that is not only of essentially a single frequency but also coherent, with the light waves all moving along in unison. Lasers consist of several components ...
