Laser is a word formed from the acronym "Light Amplification by Stimulated Emission of Radiation."
Laser beams are phase coherent and self-parallel (they do not spread out), due to the way they are created.
The use of lasers is very important in science and medicine; they have also become ubiquitous in CD-ROM and DVD players and as pointers.
