A thorough description of the physics and applications of lasers from HowStuffWorks.com.
The most common and inexpensive gas laser is the helium-neon laser and it is usually constructed to operate in the red region of light.
HiPER is a proposed European High Power laser Energy Research facility dedicated to demonstrating the feasibility of laser driven fusion as a future energy source. Read all about laser fusion and its ...
A short page dealing with the atomic explanation of lasers. Although brief and lacking detail there is a good little applet which shows what happens when an excited atom is struck by a photon.
The stimulated emission of light is the crucial quantum process necessary for the operation of a laser.
It's the laser's 50th birthday! Discover what the laser's done for you and find out what's going on near you to celebrate.
Shining light on something usually makes it hotter not colder... but not always. Find out here how you can cool things with a laser
Scientists can use lasers to find explosives in containers from a distance. They rely on using spectroscopy from the light scattered back. This is similar to the process they use to test the quality ...
The Curiosity rover conducts its first analysis of the chemical composition of rocks on Mars by firing a laser at rocks. The laser uses spectroscopy to measure what the rock is made of.
Eximer is a shortened form of "excited dimer", denoting the fact that the lasing medium in this type of laser is an excited diatomic molecule.
