In short, Light Amplification by Stimulated Emission of Radiation. Now, to explain. In a laser, there is something called a MEDIUM. This is where the photons are made. In all substances, there are atoms. In the atoms, there are electrons. The electrons are on orbits around the nucleus of an atom. There are more than one orbiting each atom. The electrons are EXCITED by getting hit by photons. The electrons absorb the energy from the photons they are hit by. To be on a certain orbit, the electron needs to have a certain amount of energy. When an electron is hit by a photon, it GAINS ENERGY so is jumps up to another orbit, because it has too much energy to stay on it's normal orbit. The electrons, though, ALWAYS have to go back to their original orbit (a law of physics) and in doing so, it needs to release energy in the form of a photon. Mirrors focus the light and it then comes out of the gun. There are more factors, but they are complicated and I cannot explain them for now. The main thing is the Excitation of the electrons then the release of the photons.

∙ 12y agoLASER is a diode that emits electrons in the .70 to .40 microns Since this cover the whole spectrum of visible light it can be of any visible color. When this diode is excited by heavy current flow it will emit light in these ranges. Usually a laser is pulsed as opposed continuous because the power dissipation of the laser itself at this hi currents

Does oxygen make things burn brighter?
Oxygen is what makes things burn at all. The more oxygen there is, the brighter it can burn.
Why is infra-red dangerous?
Infra-red by itself is not dangerous at all. It is around us everyday. But I am sure that you are actually curious about infra-red LASERS. If shined into the eyes, IR Lasers can burn and permanently damage the retinas.
What are produced when something burn?
when things burn the things that are produced are:smokeasheslight (the flames of the fire)heat (from the fire)carbon dioxide
Can the sun shoot lasers?
no because it has no lasers inside of it
Importance of living organisms of krypton?
I don't think Krypton can be in living things, It's in Lasers, and the tip of your pencil. So, i don't think Krypton is in living things.
What does the lasers do?
Burn thing and cut any thing you want
What is the difference between lasers?
well some lasers can burn and some cannot. and some that cannot are more powerful than others
Does hair lasers make your hair grow?
No it does not and it will burn you're hair off
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.
Difference between a laser and a burning laser?
Burning lasers create more heat than normal lasers. Strictly speaking, Laser include burning laser. Burning lasers are powerful laser pointers like 300mW or above, they can burn objects like paper and tapes.
What are the powers of atomix?
make things from computers come to life,lasers.
Can 5mw green lasers burn?
No they cannot burn.They can be pot modded.For burning power go with 50mw laser or more.
Things you could do with a used and dry tree?
burn it burn it burn it burn it burn it burn it
Do fraxel laser treatments burn the skin on face?
Yes. Fractional lasers can burn the face, leaving scars on the surface and even causing fat atrophy to the subcutaneous fat layer. They can burn the retina of the eye and cause damage to the thyroid.
What do you burn in Las Fallas?
you burn these things called ninots... they are things to make fun of political or famous things then they burn them. They also have thes big towers in between buldings that you can burn too.
What three common things use lasers?
DVD player, CD player and a computer
Does oxygen make things burn brighter?
Oxygen is what makes things burn at all. The more oxygen there is, the brighter it can burn.
