What is a laser in information technology?

A device that emits a highly coherent beam of light. The term stands for “light amplification by stimulated emission of radiation.” A typical laser has an active medium, which emits light, and a cavity structure, which selects certain wavelengths and directions for the emitted light.

What are 5 uses of lasers?

Lasers are widely used for laser material processing in manufacturing, e.g. for cutting, drilling, welding, cladding, soldering (brazing), hardening, surface modification, marking, engraving, micromachining, pulsed laser deposition, lithography, etc.

What is laser technology called?

light amplification by stimulated emission of radiation
LASER TECHNOLOGY. The word “laser” is an acronym for light amplification by stimulated emission of radiation and refers to devices that generate or amplify light through that principle.

How important is laser technology?

It plays an important role in, medicine, industry, and entertainment has resulted in fiber-optic communication, CDs, CD-ROMs, and DVDs. Without lasers there would be no supermarket bar code readers, certain life-saving cancer treatments, or precise navigation techniques for commercial aircraft.

What is the principle of laser?

Laser is produced by the energy released by electrons moving from high-energy to low-energy orbits , followed by the collision with excited atoms (stimulated emission) releasing 2 photons identical in wavelength, phase and in parallel. Laser light has to be absorbed by the tissue in order to exert biological effect.

What is the future of laser technology?

Soon it will be possible to generate powerful beam sources at exactly the right wavelength for all conceivable applications. Second, lasers are getting smaller. Semiconductor lasers, direct diode lasers and other lasers are steadily shrinking into miniature formats.

What is the future of laser?

For the future, the laser will evolve in many directions. It will become smaller and less powerful, in some cases down to single photon emission, if we think quantum. On the other hand, lasers will get ever more powerful, up to a region where it pulls particles out of the vacuum.

Why is laser technology important?

Laser technology is very important in the modern world because it is used in many fields, most notably measurement, where it is used to give high accuracy results in measuring small and large distances. Laser technology is also used for the purposes of generating heat in industrial cutting processes.
