The Wonder of Lasers: Great Modern Discovery and Its Principal Feature
Published by Instrument called laser gyroscopes use laser beams to detect changes in direction. These devices help ships, airplanes, and guided missiles stay on course. Another military use of lasers is in a guidance device called a target designator. A person using the device aims a laser beam at an enemy target. Missiles, artillery shells, and bombs equipped with laser beam detectors seek the reflected beam and adjust their flight to hit the spot where the beam is aimed…

Lasers can do a number of incredible things. Their special qualities make them particularly useful in recording, storing, and transmitting many kinds of information. Lasers also are valuable in such activities as scanning, heating, measuring, and guiding. As a result of their wide use, lasers can be found in equipment used in homes, factories, offices, hospitals, and libraries.

DVD
Bursts of laser light record music, computer data and other material used as patters of tiny pits in the surface of special discs. The most common of these discs, compact discs (CD’s) and DVD’s, measures about twelve centimeters across. A DVD can hold much more information than a CD can.

Disc Players
Lasers also read and play back the information recorded on these discs. In a disc player or disc drive, a laser beam reflects off the pattern of pits as the disc spins. Other devices in the player or drive change the reflections into electrical signals, which are translated into music, computer data, motion pictures, and other information. More lasers are used in disc players and drives than in any other product.

wow cool post!
i love the laser for eye surgery..coz i am near sighted. i don’t want to wear glasses anymore:)

LASIK (laser eye surgery) is awesome. I had both eyes done back in 2003, and went from ‘legally blind’ to 20/20 left and 20/25 right. It was fast (about 60-seconds per eye) and totally painless. Recovery period is extended over days and weeks, but worth it. Recovery entails avoidance of showers, diving, water-skiing, etc to protect the healing eyes for something like 3-months but really easy to do. I went to Mexico for a week about 10-days after I had LASIK done.
