Except in free electron LASERS they have every thing to do with generating LASER light. A lamp is used to excite the valence electrons of the mediums atoms to higher orbits. When a population inversion occurs the light coming out of the medium is of the same frequency and stays in a beam not diverging as incoherent light would.
Atoms, of course, have to do with everything, since everything is made of atoms.

What is the difference between cold and hot lasers?
Cold lasers are safer and deal less pain than hot lasers. Cold lasers are usually used for repairing skin damage and treating pain and inflammation. Hot lasers are simply used for burning things.
Are all lasers dangerous because they are hot?
no not all lasers are really
Where can one purchase lasers of different wavelengths?
Lasers of different wavelengths can be purchased from many sites online, such as Lexel Laser, and Wicked Lasers. Be sure to check the legality of the lasers in your country or risk losing them at customs.
What is the difference between lasers and tunable lasers?
All tunable LASERs are LASERS, however not all LASERS are tunable. In a tunable laser the lasing medium, which is typically a gas, dye or crystal, can be altered to produce slightly different frequencies, thus allowing the laser to be 'tuned' or frequency changed where most LASERS produce a very narrow band of radiation frequencies.
What devices use lasers?
There are a great many devices in the world that use lasers. Computer mice for example might use lasers to operate efficiently.
What damage can lasers do?
lasers damage call composition
Can the sun shoot lasers?
no because it has no lasers inside of it
How lasers work in road scanners?
How do lasers work
What role may lasers play in controlled nuclear fusion?
It is unclear whether this will work, but there are possibilities. One way to do this is to create so-called light wells, where interference in the light waves can trap atoms. The atoms are then moved by adjusting the light waves, possibly causing them to fuse. The technical problems with doing this are very great, and there is a significant probability it will not happen. There may be other ways of using lasers for controlled nuclear fusion.
What is the US atomic clock?
Atomic clockThe U.S. atomic clock is the NIST-F1, it began to be used in 1999 and wont lose or gain a second in 20 million years. It is a fountain atomic clock that is made of a 3-foot vertical tube inside a taller structure. It uses lasers to cool cesium atoms, forming a ball of atoms that lasers then toss into the air, creating a fountain effect. This allows the atoms to be observed for a lot longer than could be done with any previous method.
When was With Lasers created?
With Lasers was created on 2007-06-05.
When was Springfield Lasers created?
Springfield Lasers was created in 1996.
Can laser be used in plural as in lasers?
the plural of laser is lasers. for example I have many lasers. you don't say I have many laser.
Are rubies used in electronics?
Yes, rubies are used in some LASERs. These LASERs are (not surprisingly) called ruby LASERs.
What type of lasers does Erchonia manufacture?
Since the early 1970s Erchonia lasers have been classified by wavelength and maximum output powers into four classes. The lasers are used in treatment of neck and shoulder pain, breast augmentation, acne, laser assisted body augmentation. The types of lasers they use for these treatments include 3LT Lasers, Custom Design Lasers and Zerona Lasers.
What is the difference between cold and hot lasers?
Cold lasers are safer and deal less pain than hot lasers. Cold lasers are usually used for repairing skin damage and treating pain and inflammation. Hot lasers are simply used for burning things.
What lasers does Pretty Lights use?
He uses Lightwave RGB lasers
