QUANTUM ELECTRONICS --- LASER TECHNOLGY
Laser is basically a device that is able emit light through optical amplification
process that is based on the stimulated emission of electromagnetic radiation.
Laser stands for Light
Amplification by Stimulated Emission of radiation. Lasers differ from other
sources of light because they emit light coherently. Its spatial coherence allows a laser to be focused to a tight
spot, and this enables applications like laser cutting and laser lithography. Its spatial coherence also
keeps a laser beam collimated over long distances, and this enables laser pointers to work
Laser
technology is used in variety of products and technologies in use today. You'll
find them in everything from CD players to dental drills to high-speed metal
cutting machines to measuring systems etc.
