The really, really awesome Laser

By A Kid

Intro

 This report will be all on the laser.  If you know all about the laser, and you are an expert, then I don’t think you need to read this, but if you don’t know who invented the laser and all about the laser than PLEASE read this report.  It will tell you what it is, the History of it, how it works, and what the wavelengths of some lasers are.

What it is

 

This paragraph is about what a gas laser is.  According to Mary Bellis, “the first gas laser (helium neon) was invented by Ali Javan in 1960. The gas laser was the first continuous-light laser and the first to operate "on the principle of converting electrical energy to a laser light output." It has been used in many practical applications. So that is what a gas laser is.

 

This paragraph is about what a ruby laser is.  According to Matthew Weschler, “a ruby laser consists of a flash tube (like you would have on a camera), a ruby rod and two mirrors (one half-silvered). The ruby rod is the lasing medium and the flash tube pumps it.

 

This paragraph is about what the definition of laser is.  According to the dictionary, “a laser is a thing that has an intense beam of light.  It is used in drilling and cutting, alignment and guidance, and in surgery.”

 

This paragraph is about the different kinds of lasers.

According to Matthew Weschler, “there are many kinds of lasers.  Some kinds of lasers are the Solid-state lasers, Gas lasers, Excimer lasers, Dye lasers, and Semiconductor lasers.”

 

This paragraph is about what the colors of lasers are.  Lasers could be any color they could be red blue green yellow, any color.

 

This paragraph is about where you could go to play laser tag.  According to Boondocks fun center, “you could play laser tag at Boondocks fun center.”

 

History

      

This paragraph is about who invented the laser.  According to Mary Bellis, “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. Gould was a doctoral student at Columbia University under Charles Townes, the inventor of the maser. 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 his technology was exploited by others. It took until 1977 for Gordon Gould to finally win his patent war and receive his first patent for the laser.”

 

This paragraph is about when the laser was invented.  According to Mary Bellis, “the laser was invented in 1977.”

 

This paragraph is about why the laser was invented.  The laser was invented for people to play laser tag for their birthday.  Also the laser was invented for many things like, CD players, dental drills, high-speed metal cutting machines, measuring systems, tattoo removal, hair replacement, eye surgery -- they all use lasers.

 

This paragraph is about who invented the maser. 

According to kigre.com, “Charles H. Townes invented the first real maser.”

 

       This paragraph is about when the maser was invented.

According to kigre.com, “the maser was invented in the year 1951.

 

         This paragraph is about who the independent inventor of the laser was.

According to kigre.com, “the independent inventor of the laser is Joseph Weber.”

How the laser works

       This paragraph is about how the laser works.

The laser works from atoms that have electrons, a nucleus, and orbits in them.

 

       This paragraph is about how lasers are different from a normal beam of light.

According to Matthew Weschler, “the light released is monochromatic. It contains one specific wavelength of light (one specific color). The wavelength of light is determined by the amount of energy released when the electron drops to a lower orbit.

The light released is coherent. It is “organized” -- each photon moves in step with the others. This means that all of the photons have wave fronts that launch in unison.

The light is very directional. A laser light has a very tight beam and is very strong and concentrated. A flashlight, on the other hand, releases light in many directions, and the light is very weak and diffuse.”

 

Wavelength

 

       This paragraph is about what the wavelength of a ruby laser is.

According to Matthew Weshler, “a ruby laser has a wavelength of 694 nm.”

 

       This paragraph is about the wavelength of a Carbon dioxide laser.

According to Matthew Weshler, “a carbon dioxide laser has a wavelength of 10,600 nm.”

 

       This paragraph is about the wavelength of a Nitrogen laser.

According to Matthew Weshler, “a Nitrogen laser has a wavelength of 337 nm.”

      

       This paragraph is about the wavelength of a green Argon laser.

According to Matthew Weschler, “the wavelength of a green Argon laser is 514 nm.

 

       This paragraph is about the wavelength of a blue Argon laser.

According to Matthew Weschler, “the wavelength of a blue Argon laser is 488 nm.

 

       This paragraph is about the wavelength of a red Helium Neon laser.

According to Matthew Weschler, “the wavelength of a red Helium Neon laser is 633 nm.

 

       This paragraph is about the wavelength of a green Helium Neon laser.

According to Matthew Weschler, “the wavelength of a green Helium Neon laser is 543 nm.

 

       This paragraph is about the wavelength of a Yag laser.

According to Matthew Weschler, “the wavelength of a Yag laser is 1,064 nm.

 

Conclusion

So the laser is a very powerful thing made out of many atoms.  They can help people in many things and even entertain people with playing laser tag at some fun place like Boondocks.  The laser ROCKS!!!
