Gas Lasers

Intro

I am the luckiest person on earth to meet the Jonas Brothers Backstage and be at there concert did you see those wicked awesome lasers did you know that those are Gas Lasers.

In this report you will learn about who invented it and the dangers of it and how and what it is also used for and lots of other things. We are going to take this spectacular ride with Kevin, Nick, and Joe.

What The Gas Laser Can Replace

This paragraph is about what the Gas Laser has replaced. According to How Stuff works.com the Gas Laser has replaced so many things. Some of the things are when you have eye surgery back in the day they would just let you go blind because there was nothing you could do because they didnŐt have lasers but know they will use lasers and it doesnŐt hurt at all (How Stuff Works.com). They would also when you have a cavity or you need a sealant they didnŐt have lasers but know to make the stuff they put on it dry faster they have and use a laser to dry it. They also use it while youŐre at the doctor for surgery to make it go faster. As you can see Gas Lasers make things go a lot faster and as the years go by the lasers will increase. Gas Lasers are very helpful in our daily life.

 

 

Dangerous things!!

This paragraph is about the dangers of the Gas Lasers. One of the most asked questions is does the Gas Lasers let go of dangerous gases. According to Wiki.com the answer is yes they do for many different reasons but I will tell you what they are also used for later (Wiki.com). According to About.Com over 24,000 people have been killed because of the dangerous gases but half of the people who where killed were babies and other young children (About.Com).

History

         This paragraph is about the History of the gas lasers and what other things they are used for.   According to About.com the inventors of the Gas Laser are Inventors: Gordon Gould, Charles Townes, Arthur Schawlow, Theodore Maiman. These men invented it in 1917 (About.Com). According to my Dad. Some of the other ways that the Gas Lasers are used is to cut metal cut diamonds there are also used for getting your eyes checked and the are also used at the Hospital and the they are used for security (Personal Interview). They also have gas Lasers at certain schools just because the schools are very unsafe. But I have been to a school that has Gas lasers.

 

 

How It Works

This paragraph is about how the Gas Laser Works.   To get the Gas Laser to work there is usually there will be a switch of a button to turn on and off. You have to be very careful cause if you turn it on and off and on and off it will explode or brake. It may look cool but if it is not yours and you brake it costs 45,000 dollars to repair most people say that is in possible thatŐs what I thought when researched it but it was the truth for me that would be 4 months worth of allowance.

Conclusion

Thank you for listening to my Technology report. You can also go to the Internet and bye a Laser and at certain stores you can get one to. Hope you enjoyed my report. Make sure you study because you never know if later in your life you have to take a test on it or do a technology report on this.

Helium Lasers

The gain medium of the laser, as suggested by its name, is a mixture of helium and neon gases, in a 5:1 to 20:1 ratio, contained at low pressure (an average 50 Pa per cm of cavity length) in a glass envelope.

Albert Einstein did not invent the Gas Laser like some websites say.
