A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for Light Amplification by Stimulated Emission of Radiation.[1][2] 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

CIVIL APPLICATION OF LASER RANGE FINDER Synopsis: [laser is a device that emits light (electromagnetic radiation) through a process of optical amplification based on the stimulated emission of photons . Many scientific‚ military‚ medical and commercial laser applications have been developed since the invention of the laser ‚ one of these application is laser rangefinder ‚ which is a device that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates

Applications of Laser Application 1 : Defense A Laser Range Finder is an example of an application in the defense system of a country. To knock down an enemy tank‚ it is necessary to range it very accurately. Because of its high intensity and very low divergence even after travelling quite a few kilometers‚ laser is ideally suited for this purpose. The laser range finders using neodymium and carbon dioxide lasers have become a standard item for artillery and tanks. These laser range

Efectul laser Laserul este un dispozitiv optic care generează un fascicul coerent de lumină. Fasciculele laser au mai multe proprietăți care le diferențiază de lumina incoerentă produsă de exemplu de Soare sau de becul cu incandescență: * monocromaticitate — un spectru în general foarte îngust de lungimi de undă; * direcționalitate — proprietatea de a se propaga pe distanțe mari cu o divergență foarte mică și‚ ca urmare‚ capacitatea de a fi focalizate pe o arie foarte mică; * intensitate
