Laser
technology (Light Amplification by Stimulated Emission of Radiation) was
invented in 1960 by American physicist Theodore H. Maiman. Generated from solid
crystals, liquids or gases, laser beams now permeate our daily lives. In the
medical field, lasers have replaced the scalpel in certain types of surgery.
Supermarket scanners use them to read bar codes, while CD players wouldn't work
without them. Lasers have also changed the face of modern warfare; laser-guided
missiles and bombs represent the most accurate means of targeting, thus making
warfare more efficient and preventing loss of innocent life.
