Areas Laser Used

The term “LASER” is an acronym from Light Amplification by Stimulated Electronic Radiation. It employs the natural frequencies of atoms for generation or amplification of light in the visible spectrum.

1. Lasers have been introduced into radar technology. Laser range finders are used by artillery forward observers, battalion observation posts, tanks, helicopters and other vehicles that measure the distance to a target accurately. The technique involves the measurement of elapsed time between a transmitted laser pulse and a received reflected pulse.

2. Laser- guided bombs or missiles employ a laser seeker located in the nose cone of the weapon to follow a laser beam to a target illuminated by a laser designator.

3. Laser is used to detect cancer in the human body. It is also used to remove stones from the kidney and bladder.

4. Laser is used in industry for cutting and melting metals.
