What is a laser beam?

Laser beam is a stream of focused, coherent light in one wavelength. Although the word laser is generally accepted in a common language, it was originally an abbreviation for "light amplification by stimulated radiation emissions". There are many different types of lasers that are used in a wide range of technological applications, including welding and surgery. Lasers also play a role in sci -fi, where they are usually displayed as strong weapons. As it happens, the light particles called photons are released. In the normal beam of light, photons are released randomly; In the laser beam, photons are concentrated and organized. This is generally achieved by a process called stimulated emissions that occur when photons released by one atom stimulate other atoms to generate photons with the same wavelength. Most laser devices also contain mirrors that allow a light beam that repeatedly reflect, thus slowly creating a large chain reaction until the laser beam is formed. His discovery was frominitially ignored because it seemed too similar to earlier experiments involving focused light. It took a moment to realize the importance of Maiman's discovery, and finding use for this technology took longer.

Gordon Gould is also entitled to be the inventor of the laser, and there is a dispute over that one deserves the biggest credit. Gould claim that he had developed a functional laser at the end of the 1950s, but he was filed for too long. Whether Gould can be provided a loan for the development of the first real laser beam is generally recognized as the first man to use Laser.

In the first days, laser beams were mostly used as a replacement for other concentrated lighting technologies that were available at the time. Scientists quickly developed some ideas for laser applications, but it took some time to iron some technical problems. The lasers set out over timeEven many devices that the average person can encounter every day. Some common laser technologies include barcode readers, DVDs and safety systems. The laser beam also had an impact in the world of medicine by allowing doctors to perform fine operations that would not be possible without fine control and accuracy that lasers provide.
