Laser

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". The first laser was built in 1960 by Theodore H. Maiman at Hughes Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light coherently. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers. Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum, i.e., they can emit a single color of light. Temporal coherence can be used to produce pulses of light as short as a femtosecond.

Among their many applications, lasers are used in optical disk drives, laser printers, and barcode scanners; fiber-optic and free-space optical communication; laser surgery and skin treatments; cutting and welding materials; military and law enforcement devices for marking targets and measuring range and speed; and laser lighting displays in entertainment.

Laser Beams

by: Wintersleep

One day laser beams will cure my sight
Negative five, that's pretty much blind
I wanna see what you know.
Stare so deep into the laptop light
Sip your coffee and stare
Like you got somethin to say, but you can't say it
Cause it just ain't there anymore.
The vike premonition flexed in its might
Converse with absolute time, and space
And time and space and time and space and nothin really matters anymore.
You can't say it, don't ever say it
Its not tangable, it's not even relevant
A warm hand, a short skirt, a soft blanket, a trusty appliance
A fifty-seven in mathematics
An oxygen mask, they'll stick it and never come back
They'll never come back, they'll never come back anymore.
Are you with me and am I wrong?
These silly old songs, do they mean anythin or am I just wrong?
Am I just wrong, am I just wrong?
How did I ever get so God damned dumb?
A forigen lick from a familiar tongue.
Its not one you love, but its familiar enough
Mouth full of teeth chewed up and spit on the ground
When I speak I'm not words, just white naked sound
Carelessly rendered, scattered around.
Random.
Animal.
Clumsily stitched together.
Forever alien and forever altered
