Light amplification by the simulated emersion of radiation

Intro

Well this is an exciting and important report and it will be on our final grade. This will be extremely important as a say again but lasers are very important and helpful and they form Metallica laser light shows and other things like laser hair removal or laser eye surgery . So pleas pay attention.

Lasers

How far can lasers go? According to Hetch, Jeff. There is a laser beam that is 12 million miles in distance from a spacecraft to earth. Lasers can travel really short distances depending on how they are used. Some are used in every day life, for example CD players, eye surgery, laser light shows and a computer mouse. Many things and travel a variety of distances can use lasers.

 

What are lasers?

       This paragraph is what lasers are and were.

According to wiki answers.

         Lasers are used to cut, eye surgery, and laser hair removal they used to only use them for entertainment and to see things in the dark it was also used to cut metal and it still is but lasers are actually little atoms that get excited and produce a color in a single stream of light. 

 

History of lasers

The name LASER is an acronym for Light Amplification by the Stimulated Emission of Radiation. In 1917, Albert Einstein first theorized about the process, which makes lasers possible called "Stimulated Emission." In 1958, Charles Towns and Arthur Schawlow theorized and published papers about a visible laser, an invention that would use infrared and/or visible spectrum light, however, they did not proceed with any research at the time. Gordon Gould was the first person to use the word "laser". There is good reason to believe that Gordon Gould made the first light laser. Gordon Gould was inspired to build his optical laser starting in 1958. He failed to file for a patent his invention until 1959. As a result, Gordon Gould's patent was refused and others exploited his technology. It took until 1977 for Gordon Gould to finally win his patent war and receive his first patent for the laser.

Here are picks of lasers

Conclusion 

Well the stuff IÕve gone over is how far lasers can go and what they are so come back next time so we can have this much fun.
