  Laser - Wikipedia, the free encyclopedia
For a laser to operate, the gain medium must be "pumped" by an external energy source, such as electricity or light (from a classical source such as a flash lamp, or another laser).
Lasers are also used for dermatological procedures including removal of tattoos, birthmarks, and hair; laser types used in dermatology include ruby (694 nm), alexandrite (755 nm), pulsed diode array (810 nm), Nd:YAG (1064 nm), Ho:YAG (2090 nm), and Er:YAG (2940 nm).
Furthermore, science-fiction film special effects often depict weapon laser beams propagating at only a few metres per second—i.e., slowly enough to see their progress, in a manner reminiscent of conventional tracer ammunition—whereas in reality a laser beam travels at the speed of light, and would be instantly visible along its entire length.

Laser weaponry, scientific and materials research, laser used in the U.S. military's Airborne laser, operated in continuous wave mode and capable of extremely high powers in the megawatt range.
Nd:Glass lasers are usually frequency tripled to the third harmonic at 351 nm in laser fusion devices.
This material is often used in highly-tunable mode-locked infrared lasers to produce ultrashort pulses and in amplifier lasers to produce ultrashort and ultra-intense pulses.

A laser (light amplification by stimulated emission of radiation) is a device which uses a quantum mechanical effect, stimulated emission, to generate a coherent beam of light.
Light from a laser is often very collimated and monochromatic, but this is not true of all laser types.
The basic physics of lasers centres around the idea of producing a population inversion in a laser medium by 'pumping' the medium; i.e., by supplying energy in the form of light or electricity, for example.

Laser-core, which is constructed of laser welded aluminum honeycomb core, is built to resist carbon build up, often a problem with plastic alternatives, Additionally, it results in cleaner laser cuts, allows for less debris to build up inside of it, and is built to last.
Lasers, like many of our inventions, first came to existence in laboratories where scientists discovered that, by creating a light source and focusing the energy, one could produce a medium powerful enough to burn through certain materials.
This is the language of the laser engraver.

 Laser   (Site not responding. Last check: 2007-10-08)
A laser (light amplification by stimulated emission of radiation) is a device which uses a quantum mechanical effect, stimulated emission, to generate a coherent beam of light from a lasing medium of controlled purity, size, and shape.
By contrast, a laser generally emits photons in a narrow, well-defined, polarised, coherent beam of near-monochromatic light, consisting of a single wavelength or hue.
The beam emitted by a laser often has a very small divergence (highly collimated) though a perfectly collimated beam cannot be created, due to the effect of diffraction, a laser beam will spread much less than a beam of light generated by other means.
