Police laser uses laser light pulses rather than radar radio waves for speed detection. The laser speed gun has found its way into the hands of state and local police in at least half the country. The advantages of a laser gun are compelling: the laser light beam is far narrower than a radar beam, allowing more accurate pinpointing of a specific vehicle; and the time needed for capturing a speed reading is less than half a second versus 2 to 3 seconds for radar. The drawbacks are also important to note: laser guns are very expensive, they can't be used from a moving vehicle or from behind glass, and accurate aiming requires a tripod or a very steady hand. Despite initial claims that the energy from a laser gun is not detectable, it is. And as the laser beam moves away from the laser gun, it widens and becomes easier to detect. Vehicle speeds are typically measured at roughly 1,000 feet (1/5 mile); at that distance the laser beam is over 3 feet wide.

An acronym of light amplification by stimulated emission of radiation. A laser is a cavity, with plane or spherical mirrors at the ends, that is filled with lasable material. This is any material - crystal, glass, liquid, dye or gas - the atoms of which are capable of being excited to a semistable state by light or an electric discharge. The light emitted by an atom as it drops back to the ground state releases other nearby, excited atoms, the light being thus continually increased in intensity as it oscillates between the mirrors. If one mirror is made to transmit 1 or 2 percent of the light, a brilliant beam of highly monochromatic, coherent radiation is emitted through the mirror. If plane mirrors are used, the beam is highly collimated. With concave mirrors, the beam appears to emerge from a point source near one end of the cavity. Learn more about Laser...

A medical instrument that concentrates light into an intense, narrow beam for use in surgery, to diagnose disease, and in cancer therapy; acronym for Light Amplification by Simulated Emission of Radiation
An acronym for Light Amplification by the Stimulated Emission of Radiation. A commonly used tool for cosmetic and surgical procedures.
The laser is an intense coherent light beam with very narrow bandwidth used in digital imaging devices to produce images by electronic impulses from computers.
The acronym for light amplification by stimulated emission by radiation. The laser is an intense light beam with a very narrow band width that can produce images by electronic impulses. It makes possible imaging by remote control from computers or facsimile transmissions.
Is an acronym for Light Amplification by Stimulated Emission of Radiation. A laser is a cavity, with mirrors at the ends, filled with material such as crystal, glass, liquid, gas or dye. It is a device that produces an intense beam of light with the unique properties of coherence, collimation and monochromaticity.
Most people now know what a laser is: a powerful, amplified beam of light that can cut through steel or tissue with ease. The laser discussed in this book is specially tuned to affect only materials that form stones. Normal tissue is not harmed. The laser is a powerful tool to fragment stones, but it requires direct contact with the stone through some sort of telescope in either the kidney, ureter or bladder.
A light source producing, through simulated emission, coherent, near monochromatic light. Lasers in fiberoptics are usually solid-state semiconductor types.
A device that transmits an extremely narrow and coherent beam of electromagnetic energy in the visible light spectrum. Used as a light source for fiber-optical transmission (generally more expensive, shorter lived, single mode only, for greater distances than LED).
An acronym for light amplification by stimulated emission of radiation. A device utilizing natural oscillation of atoms or molecules between energy levels for generating coherent electromagnetic radiation in the ultraviolet, visible or infrared regions of the spectrum.
light amplification by stimulated emission of radiation. Analog transmission device in which a suitable active material is excited by an external stimulus to produce a narrow beam of coherent light that can be modulated into pulses to carry data. Networks based on laser technology are sometimes run over SONET.
Acronym meaning light amplification by stimulated emission of radiation.
Light amplification by the stimulated emission of radiation. A laser is a coherent, monochromatic light source produced by directing a light beam repeatedly through an active material so that it becomes amplified, and then directing the beam into a narrow cone of divergence. The active material converts energy into laser light, a pumping source provides power or energy, and separate optics direct the beam through the active material and then into a narrow cone of divergence.
(Light Amplification by the Stimulated Emission of Radiation) A device that creates a narrow, intense and coherent light. Many lasers deliver light in an almost-perfectly parallel collimated beam that is very pure, approaching a single wavelength.
Acronym for light amplification by stimulated emission of radiation. A light source that produces, through stimulated emission, coherent, near monochromatic light.
A device that produces monochromatic, coherent light through stimulated emission. Most lasers used in fibre optic communications are solid-state semiconductor devices....An acronym for Light Amplification by Stimulated Emission of Radiation.... A device which transmits an extremely narrow and coherent beam of electromagnetic energy in the visible light spectrum. See also: Injection Laser Diodes, Stimulated Emission.
or LASER n. Acronym for light amplification by stimulated emission of radiation. A device that uses certain quantum effects to produce coherent light, which travels with greater efficiency than noncoherent light because the beam diverges only slightly as it travels. Lasers are used in computer technology to transmit data through fiber-optic cables, to read and write data on CD-ROMs, and to place an image on a photosensitive drum in laser printers.
Device that produces a very narrow intense beam of light. The name is an axcronym for "light amplification by stimulated emission of radiation.
A LASER (acronym for Light Amplification by Stimulated Emission of Radiation) is an optical source that emits photons in a coherent beam. The term has since entered the English language as a standard word, laser, losing the capitalization in the process.
