The term laser is an acronym for light amplification by stimulated emission of radiation. The laser beam is strong, narrow, monochromatic, and the direction of the beam of electromagnetic radiation. Often these beams in the spectrum of visible light. The laser laser stimulates the atoms in the middle. The electrons in the atoms are moved to a higher orbit and let photons, creating a laser beam.
History
In 1957, a student of at Columbia University, called Gordon Gould developed the first laser. His mentor, Charles Townes, designed and built a device called Masers, the microwave instead of light, used to produce a coherent beam of electromagnetic radiation. Townes also optical Maser intended and so many people have was also credited with the invention of the laser. Gould began a war of patents, which lasted until 1977, when he finally won his first patent for a laser.
Type
Laser types including gas, liquid and solid. Gas laser excites the electrons in a gas such as helium, neon, cadmium, carbon dioxide and nitrogen. A laser which organic liquid dye molecules used to generate the waves of radiation that can be set includes coloring liquid laser. Solid laser including Ruby lasers, to use the gems to produce a beam of light red.
Function
Ray laser laser is most commonly used in devices from CD and DVD, optical scanners, mice, printers, and pointer used. They are also used to produce the hologram. The laser beam used in industry for cutting and welding of metals and to check the land and the construction of buildings. In scientific research, which used in spectroscopy, laser and chemical analysis. They are used in medical procedures such as surgery of the eyes perform cancer and heart, as well as cosmetic procedures. Dental technology, including the treatment of caries, neural regeneration and remodeling of the gingival tissue.
Advantages
A laser beam can store and play back still images of high quality, video, audio, and computer data storage. You can measure distances with high accuracy. A scanner laser in the store to save time in the price of the product and the customer of the purchase process. The industry is cutting and welding laser faster and more accurately than other methods. Laser of less scalpels and exercises damages in medical and dental procedures. Communication and data processing has led to advances in the real world, such as fibre-optic telephone networks, scientific research using lasers.
The effect of
A laser beam in normal have led to advances in laser technology. We use the laser every day, often without noticing that we do. Future advances in laser technology undoubtedly generated improvements in the area of entertainment, medicine, dentistry, science, defence and telecommunications. The laser will be able to produce energy for the foreseeable future.
