works the word "laser" stands for "light amplification by stimulated emission of radiation." Lasers are possible because of the way
light interacts with electrons |
|
How lasers work
The laser uses a process called stimulated emission to amplify light waves. (One
method of amplification of an electromagnetic beam is to produce additional
waves that travel in step with that beam.) |

Introduction to
lasers ordinary natural and artificial light is released by energy changes
on the atomic and molecular level that occur without any outside intervention. A
second type of light exists, however, and occurs when an atom or molecule
retains its excess energy until stimulated to emit the energy in the form of
light |

fundamentals the word "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation.
Lasers are finding ever increasing military applications -- principally for target acquisition, fire control, and training. These lasers are termed
rangefinders, target designators, and direct-fire simulators. Lasers are also being used in communications, laser radars (LIDAR), landing systems, laser
pointers, guidance systems, scanners, metal working, photography, holography, and medicine |
