Lasers :: essays research papers

The laser is one of the most advanced tools we bedevil in our civilization. Lasers are powerful enough to cut with a duncical piece of steel, yet can be utilize in aesculapian surgery. Lasers are gived in the army, for guns, for range finding and a solid lot more.Most people dont know where the bringing close together of the laser came from. The idea for the laser came from a machine called a maser. The maser was a tool that was subject to strengthen, or amplify radio and light waves. The first laser was make in California in 1960.

This includes entertainment, military, communication, businesses, measurement, cutting, and more.Measurement Lasers have become an important part of measurement. A laser is the fastest way to measure long distances. This use can be applied in construction work and astronomy.Cutting A laser is also abundant for cutting intentions. It can get 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 petite surgical procedures. It is used by jewelers to cut diamonds, gold, silver, platinum, etc....It is also used in corporations in which cutting metal or fine cutting is involved.communicating The way the laser is used in the field of communication is through fiber optics.
