LASERS Gordon Gould is the inventor of the Laser. He came up with the name LASER (Light Amplification by Stimulated Emission of Radiation). He invented the laser in 1957 but failed to get a patent. He had everything written in his notebooks and had it notarized, thinking it would be safe until he came up with a working model. He spent many years fighting in court to get credit for his work.Gould was born in New York City, on July 17, 1920. He graduated with a degree in physics. He worked for the United States on the Manhattan Project, building an Atomic bomb during World War ll.At the same time that Gould was working on the stimulated emission of radiation at Columbia University in New York , another man, Charles Townes, was also working on it. But it was Gould who thought of adding an optical resonator to a tube that has mirrored ends. This was the way to make amplified light. Another scientist Theodore Maiman was the first to demonstrate a laser. He applied for the patent and got it even though it was Gordon Gould's idea. Gould didn't think he could get a patent until he had a working model so he took his notebook with all his ideas about the laser and had it notorized. He wanted to get credit for the laser and have the patent for it so with the help of an investor, who paid legal fees, Gordon Gould was finally able to win his legal cases in 1977 and given ownership of the laser patent. In 1978 he was named Inventor of the Year.Lasers are many different sizes. They can be as large as a football field or as small as a grain of salt.The laser has three main parts.1. An energy source- Lasers often use electricity, another laser or a flash lamp as its supply for the energy source 2. An active medium- This is a material that can be made to create laser light. Gases, liquids or solids can be used. The active medium absorbs...

Lasers: death rays or miracle breakthroughs?

645 words - 3 pages Lasers can now improve health and personal appearance. They can erase wrinkles, scars, and smooth fine lines around people's faces. They can also remove discolorations on skin, broken blood vessels, and unwanted hair. Mild or moderate acne can also be treated by lasers. One of the most common uses is laser eye surgery. The lasers sculpt the surface of the cornea and this treatment allows people to see without glasses. Barron's magazine says that

1610 words - 6 pages Refracting Lasers?Lasers are very important in our world today; but not too long ago, we did not have them! The main reason they did not think of them before the 1900's was because scientists did not know about stimulated emission. But in the early 1900's Albert Einstein was the first to describe this process. The next major breakthrough in lasers was when Charles H. Townes created a population inversion, which is needed to create stimulated

The Impact of the Lasers Technology on Society

972 words - 4 pages Introduction:The name LASER is an acronym for Light Amplification by the Stimulated Emission of Radiation. In 1917, Albert Einstein first theorized about the process which makes lasers possible called "Stimulated Emission." In this paper, we can view the impact of the lasers technology on society from four perspectives: the strength, the weakness, the opportunity and the threat of Lasers Applications. To sum up, we will focus on the future of

Lidar System

553 words - 3 pages LIDAR, stands for Light Detection And Ranging, is an active optical remote sensing instrument. It is an innovative technique that uses laser for probing the planetary atmosphere [1, 2, and 3]. Atmospheric LIDARs use narrow pulsed lasers. Flash-lamp pumping is generally employed in generation of Q-switched lasers. Flash-lamp pumped (FLP) systems produce lasers at low repetition rate with high pulse energies. Several problems such as limited life
