New applications of laser technology are being developed constantly. Laser engineering was long the stuff of science fiction, but today it's found in dental drills, CD players, laser saws, high-speed metal cutting machines, testing methods and a number of other items.
The phrase laser means Light Amplification by the Stimulation Emission of Radiation. In 1916, Albert Einstein developed the idea of Stimulated Emission. Just set, it is a procedure where a photon is emitted from an and crashed into other atoms, producing photons to be also emitted by them. In a chamber, more and more photons jump around, increasing the power level within the chamber. As a narrow beam of light If the energy has built up sufficiently, it exits the chamber. until, in 1954, Charles Townes, an American physicist, began examining microwave light While Einsteins work was discovered during the 1920s, it was largely neglected.

The 60s heralded new innovations in laser technology. Theodore Maiman built the initial working visual light laser in 1960. It used a good state laser that included a synthetic ruby. The initial semiconductor laser was developed in 1962.
Today, the three most frequent lasers are fuel, strong state and semiconductor.
Helium-neon lasers
Helium-neon lasers will be the cheapest visible light lasers. In 1974, these were used as bar code scanners, first in food stores and now in several large retail stores. The laser is scanned across a bar code and tells the cost to the cash registers computer of the piece. Supply and It may also provide information on purchase reductions, stock numbers.
Lasers are employed by machinists and surveyors to measure distance and align areas. They're used to measure the speed of light in a laboratory, miles on a road or motion along an earthquake fault.
Argon lasers
Argon lasers are used by the medical profession to make incisions that are more specific than scalpels. There's less scarring with lasers simply because they can be utilized instead of sutures to blend the cut together after surgery. Lasers are used in eye surgery to weld the retina back together. Lasers are also used to correct bad vision by reshaping the cornea. One of the newest medical uses for lasers is to make small holes in the center in order that paths are created for new blood flow. This helps prevent heart attacks. The only real downside may be the increased cost over old-fashioned procedures.
Argon lasers make holograms, and are used in spectrochemistry, visual picture processing, semiconductor processing and laser light shows.
Solid state lasers
Solid state lasers are used for chopping, welding, heat treating and marking of materials. Dealers may do very specific reductions when working with lasers to reduce good jewels. Better cuts are allowed by lasers on metals and the welding of different metals.
Scientists use solid state lasers to discover the slightest movements in matter. Police has long applied laser technology for considering the speed of cars. The army is using solid state lasers in rangefinders, laser guided bombs and satellite communications systems.
The biggest lasers on the planet are solid state lasers. Most of the laser projectors for light displays and for other laser features use solid state in the place of argon or krypton gas lasers.
Semiconductor lasers
Semiconductors are used to make lasers with invisible light. The first successful consumer product to incorporate a, the laserdisc person, was introduced in 1978. In 1983, the compact disc player was presented. Currently, lasers will also be used in cell phones, DVD players, laser printers and wireless Internet transmission.
