Lasers :: essays research papers

The optical maser is wizard of the most advanced tools we have in our civilization. Lasers are all-powerful adequate to cut through a thick piece of steel, yet prat be procedured in medical surgery. Lasers are utilize in the army, for guns, for range finding and a whole lot more.Most passel dont know where the idea of the laser came from. The idea for the laser came from a appliance called a maser. The maser was a tool that was able to strengthen, or amplify piano tuner and light waves. The first laser was make in California in 1960.

They had think of some word or delivery to described it. They came up with Light Amplification by Stimulated firing of Radiation. Using the first letter of each main word they named it laser. The laser had everyone excited.The laser was put through many tests and experiments to see what it could do to helper modern civilization. At first there werent many uses for the laser. Then in the 1970s it became very important. It was finally being used in everyday life. As years went on the uses grew in number.Today lasers were being used in a variety of ways.

A laser is the fastest way to measure long distances. This use can be applied in construction work and astronomy. parapraxis A laser is excessively great for cutting objects. It can seduce to those hard to reach places by the use of mirrors to bend the beam of light. It also is strong enough to cut through solid steel. A laser never damages the surface of the object because it never touches it. Lasers have beenused in both large and small surgical procedures. It is used by jewelers to cut diamonds, gold, silver, platinum, etc....It is also used in corporations in which cutting surface or fine cutting is involved.Communication The way the laser is used in the field of communication is through fiber optics.
