By Funky Monkey

Intro

Lasers.  When some people hear this word they think it means means, fun, flashlight thing, but there are many more things that they can do. (They are fun) For some of you,  teachers may think itŐs a teaching tool you use to point out things with.  For you mischievous kids you may think, some thing to trick your friends with.

History and Future

What it is and how it works

Do you know about lasers? Laser stands for light amplification by simulated emission of radiation. Kind of hard to remember!  Enough of that hard brain work! According to Photon inc. ŇTheoretically, light consisting of just one wavelength. No light is absolutely single frequency since it will have some bandwidth. Lasers provide the narrowest of bandwidths that can be achieved.Ó  Or in other words a regular light is made up of wavelengths that spread, or they are not close together, a laser however has one wavelength that goes in one direction.

Have you ever heard some cool laser facts? Do you know that according to Physorg.com the longest laser is 75 kilo!! And according to popular mechanics the shortest laser is (you wont believe this) barley a hundred-millionth of a millimeter a cross! That is pretty big and pretty small
