Hey my report is on lasers! I am going to tell you what lasers are the history of them and how it works. I hope you learn something from my report! Enjoy!

*What it is*

       Hey, do you know fast a Laser is! According to Laser Tec. it can profile a vehicle’s shape traveling 120 mph without missing a beat.  (http://www.lasertech.com/Speed_Enforcement/Traffic/Profiling_Classification.htm) How cool is that! I wonder though, does it work so well that it can see the license plate?  120 is faster than any speed limit I know is. I’d feel bad for the next person that speeds, because they could be caught pretty easily.

         Do you know what else lasers are used for? According to noble web “1971 Gabor (alone) was given the prize, having founded the basic ideas of the holographic method, which is a famous and spectacular application of laser technology. At first "just" a method of creating 3-D pictures, it has since become a useful tool for the observation of vibrating objects. Much of what we today know about how musical instruments produce their tones is due to the use of holograms.” (http://nobelprize.org/educational_games/physics/laser/facts/history.html) How awesome is that! I never knew that they used lasers to holograph.

       How does Laser Light Differ from Other Light?  According to noble web “Light is really an electromagnetic wave. Each wave has brightness and color, and vibrates at a certain angle, so-called polarization. This is also true for laser light but it is more parallel than any other light source. Every part of the beam has (almost) the exact same direction and the beam will therefore diverge very little. With a good laser an object at a distance of 1 km (0.6 mile) can be illuminated with a dot about 60 mm (2.3 inches) in radius.” (http://nobelprize.org/educational_games/physics/laser/facts/index.html)  I never knew that either. I didn’t  know it could go that far either.          


Do you want to know what laser stands for? Well, According to Mary Bellis “The name LASER is an acronym for Light Amplification by the Stimulated Emission of Radiation.” (http://inventors.about.com/od/lstartinventions/a/laser.htm)


How it Works

This Paragraph is going to tell you how lasers help with building. According to Laser inc. Technology “a laser Releases yourself from the constraints of chains, measuring tapes and prism poles. Let the power and convenience of reflector less laser technology take you places you could never go before.” (www.http://www.lasertech.com/profmeasurement.html) Talk about helpful! If I were to build something I would want one!

What exactly does the laser do to help builders build stuff? According to Laser inc. Tech. “at Laser Technology, we design compact, lightweight and rugged measurement tools which are easy to operate. This especially holds true for our Impulse lasers which measure long-range distances and heights. (http://www.lasertech.com/profmeasurement.html) To me things like this are awesome. Learning more and more is cool.


So that is my report. For how it works, history, and what it is. I hope you learned as much as I have reading my report! Thanks again!
