New applications of laser technology are now being developed constantly. Laser engineering was long the stuff of science fiction, but today it is utilized in dental exercises, CD players, laser saws, high-speed steel cutting machines, testing systems and a host of other services and products.

The term laser means Light Amplification by the Stimulation Emission of Radiation. In 1916, Albert Einstein developed the theory of Stimulated Emission. Only put, it is a process where a photon is emitted from an and crashed into other atoms, causing photons to be also emitted by them. In a chamber, more and more photons jump around, increasing the energy level within the chamber. If the power has built up enough, it leaves the chamber as a narrow beam of light. until, in 1954, Charles Townes, an American physicist, started analyzing microwave light Although Einsteins work was explored through the 1920s, it was largely forgotten.

The 60s heralded new discoveries in laser technology. Theodore Maiman built the initial working visual light laser in 1960. It used a good state laser that involved a synthetic ruby. The very first semiconductor laser was made in 1962.

Today, the three most frequent lasers are semiconductor, strong state and gas.

Helium-neon lasers

Helium-neon lasers will be the cheapest visible light lasers. In 1974, they certainly 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 shows the cash registers computer the price of the piece. Inventory and information can be also provided by it on purchase reductions, stock figures.

Lasers are used by machinists and surveyors to measure distance and arrange components. They're used to assess the speed of light in a laboratory, miles on a road or movement along an earthquake fault.

Argon lasers

Argon lasers are utilized by the medical profession to create incisions that are more exact than scalpels. There's less scarring with lasers since they can be used in the place of sutures oxy fuel cutting equipment to blend the incision together after surgery. Lasers are employed in eye surgery to weld the retina back together. Lasers will also be used to correct poor vision by reshaping the cornea. One of the latest medical uses for lasers would be to make small holes in the heart so that trails are manufactured for new blood circulation. This can help prevent heart attacks. The only real disadvantage is the increased cost over conventional procedures.

Argon lasers make holograms, and are employed in spectrochemistry, visual picture processing, semiconductor processing and laser light shows.

Solid state lasers

Solid state lasers are utilized for chopping, welding, heat treating and marking of materials. Jewelers can do very precise cuts when utilizing lasers to reduce great jewels. Better cuts are allowed by lasers on metals and the welding of dissimilar metals.

Scientists use solid state lasers to discover the slightest movements in matter. Law enforcement has long used laser technology for considering the speed of vehicles. The military is employing solid state lasers in rangefinders, laser guided bombs and satellite communications systems.

The biggest lasers in the world are solid state lasers. Most of the laser projectors for light shows and for other laser shows use solid state in the place of argon or krypton gas lasers.

Semiconductor lasers

Semiconductors are accustomed to make lasers with hidden light. The very first successful consumer product to include a, the laserdisc person, was released in 1978. In 1983, the compact disc player was presented. Currently, lasers will also be utilized in DVD players, cell phones, laser printers and wireless Internet transmission.
