Light Amplification by Stimulated Emission of Radiation.
A "laser" is a light source created when a light amplifier is placed between a pair of mirrors. The mirrors bounce the light back into the amplifier, producing feedback, and the amplifier repeatedly amplifies the light as it passes back and forth. To let the light escape from between the mirrors, one semi-transparent mirror is used on one end.
Laser light is very pure in frequency (called "monochromatic.") Laser light also behaves as if it comes from a single point (called "spatial coherence.) Laser light is not necessarily intense, and not necessarily parallel. However, because laser light comes from a single point, a lens can concentrate the light back down to form an intensely bright point. Or, the bright point of light can be projected into the distance, forming a narrow parallel beam.
Lasers are used for highlighting lights in presentations, and sold as toys in mild form, they can also be used in many industrial applications and weapon systems. Common industrial lasers use a CO2 or YAG tube to run CNC machines capable of cutting and marking plastic, metal, and other materials. Also used in the medical industry for surgical procedures.

laser
The old laser printers used He-Ne laser , and the modern laser printers use infrared laser .
Laser pointers and laser pens are basically the same thing. A laser pen is a laser pointer with a pen attached.
laser is written the same way in french as in English laser-laser
Low level laser also referred to as a cold laser.
The word laser is a noun. It can be used in a sentence such as, "He pointed the laser at the screen when making a presentation." Laser can also be used as an adjective, such as in laser gun or laser beam.
No it won't. Laser pointer simply emit a laser beam whereas laser tag systems use other methods to register tags. The laser in laser tag is for effect. The actual laser doesn't tag the pack.
