How Lasers Work

"Laser" is an acronym which stands for Light Amplification by Stimulated Emission of Radiation. A laser is a device which produces a beam of very bright and powerful light, will all the photons vibrating at the same speed.
There are many different types of lasers like a Ruby Laser and Lasers you see in futuristic shows. But I'll be sharing how a Ruby Laser work. Basically a Ruby Laser comprise of the following: A Mirror, A Partly Mirrored Surface, A Flash Tube and a Solid Ruby Crystal (Hence the name of the Laser), cylindrical in shape.

Here's a very basic explanation:
The Flash Tube is coiled round a Ruby Crystal. Inside the Ruby are atoms that contain some energy. When a light shines through the ruby crystal, the atoms in the ruby get excited, having more energy. The excited atoms then give off light. The Light is reflected by mirrors at each end of the tube, making other atoms release light energy as well. This intense light leaves the tube as a burst of laser light.

Well, thats it. Hope you enjoyed it! My next post should be about Psychic Energy Fields or Electromagnetic Fields (EMF), but I hold no guarantees!

First Post

Ok, hello all you happy people! My post regarding physics and stuff will be coming soon. Just a sneek peek: My post would be about the theme of my blog. Ok...uhh...bye.
