The word laser is an acronym , the letters standing for Light Amplification by Stimulated Emission of Radiation. Lasers work as a result of resonant effects. The output of a laser is a coherent electromagnetic field. In a coherent beam of electromagnetic energy, all the waves have the same frequency and phase.
The acronym laser stands for "light amplification by stimulated emission of radiation." Lasers work as a result of resonant effects. The output of a laser is a coherent electromagnetic field. In a coherent beam of electromagnetic energy, all the waves have the same frequency and phase.
In a basic laser, a chamber called a cavity is designed to internally reflect infrared (IR), visible-light, or ultraviolet (UV) waves so they reinforce each other. The cavity can contain gases, liquids, or solids. The choice of cavity material determines the wavelength of the output. At each end of the cavity, there is a mirror. One mirror is totally reflective, allowing none of the energy to pass through; the other mirror is partially reflective, allowing approximately 5 percent of the energy to pass through. Energy is introduced into the cavity from an external source; this is called pumping.
As a result of pumping, an electromagnetic field appears inside the laser cavity at the natural (resonant) frequency of the atoms of the material that fills the cavity. The waves reflect back and forth between the mirrors. The length of the cavity is such that the reflected and re-reflected wavefronts reinforce each other in phase at the natural frequency of the cavity substance. Electromagnetic waves at this resonant frequency emerge from the end of the cavity having the partially-reflective mirror. The output may appear as a continuous beam, or as a series of brief, intense pulses.
The ruby laser, a simple and common type, has a rod-shaped cavity made of a mixture of solid aluminum oxide and chromium. The output is in pulses that last approximately 500 microseconds each. Pumping is done by means of a helical flash tube wrapped around the rod. The output is in the red visible range.
The helium-neon laser is another popular type, favored by electronics hobbyists because of its moderate cost. As its name implies, it has a cavity filled with helium and neon gases. The output of the device is bright crimson. Other gases can be used instead of helium and neon, producing beams of different wavelengths. Argon produces a laser with blue visible output. A mixture of nitrogen, carbon dioxide, and helium produces IR output.
Lasers are one of the most significant inventions developed during the 20th century. They have found a tremendous variety of uses in electronics, computer hardware, medicine, and experimental science.
Lazer Stands for light amplification simulated emission radiation and it is not actually z it is s we just say z for lazer.
Light Amplification by Stimulated Emission of Radiation.
Lazer is a misspelling of LASER. There are no acronyms for "LAZER", however, there are acronyms for "LASER". A popular one is Light Amplification by Stimulated Emission of Radiation.
LASER = Light Amplification by Stimulated Emission of Radiation.
Light Amplification by Stimulated Emission of Radiation
Light Amplification by Stimulated Emission of Radiation
The correct word is LASER. = Light Amplification of Stimulated Emissions of Radiation. -( You cannot spell 'stimulated' with a Z)
Light
It stands for Army laser weapon simulation
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.
The word laser is only informally used as a verb, with the past tense "lasered." (fired or shot with a laser)
XLT has many different meanings. Some of them include Microsoft Excel Template, Xerox Lexical Technology, Xenon Laser Tube, and Extra Large Telescope.
The full form of laser is Light Amplification by Stimulated Emission of Radiation.
nm means nanometer, that being the wavelength of that laser.
LASER is an acronym. It stands for Light Amplification by Stimulated Emission of Radiation.
LASER is an abbreviation, meaning "light amplification through stimulated emission of radiation".
A laser profilometer is used for construction control surveys. Laser profilometers are non contact instruments, meaning they don't need to touch the surface.

It stands for Army laser weapon simulation
The list of weapons that start with laser are: Laser axe Laser bow Laser chaingun Laser chainsaw Laser cannon Laser crossbow Laser daggers Laser gatling gun Laser knife Laser machete Laser machine gun Laser rapier Laser rocket launcher Laser scythe Laser shotgun Laser slingshot Laser sword Laser tommy gun Laser whip and countless others
As opposed to radio, laser is highly focused. Meaning that as long as you can keep the beam aimed at the receiver, it's easier to prevent others from learning whats being transmitted
L= light A= amplification by S= stimulated E= emission of R= radiation

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.
