How does laser sources work?

Question

I need some schemes, pictures to make a presentation at a college level about Laser Sources.

Answer 1

This is the method of converting incident electromagnetic radiation of mixed frequencies to one or more discrete frequencies of highly amplified and coherent ultraviolet, visible, or infrared radiation.

Here is a source where you can find ample pictures and explanations on this subject that will definitely help you to prepare slides, etc. for your forthcoming presentation. If you want to lelnghthen your presentation include some facts about maser [m (icrowave) a (mplification by) s (timulated) e (mission of) r (adiation).] as well

1. http://en.wikipedia.org/wiki/Laser
2. http://scienceworld.wolfram.com/physics/Laser.html
3. http://en.wikipedia.org/wiki/Maser

These sites have other links, names of books and articles that may help you further in your work.

Have a nice time

Answer 2

Laser action is explained by the theories of quantum mechanics and thermodynamics. Many materials have been found to have the required characteristics to form the laser gain medium needed to power a laser, and these have led to the invention of many types of lasers with different characteristics suitable for different applications.

Answer 3

Start with where 'LASER' comes from: Light Amplification by Stimulated Emission of Radiation. Certain crystals and gases have natural properties of resonating coherent wavelengths of light.
