Gordon Gould proposed laser action, then not long after 4 years, in 1960, first laser was build by Theodore Maiman. Besides that, Gordon also derived the word laser from “light amplification by the stimulated emission of radiation”. The laser developer look amplification is very important as a step to build a laser, so these people make one advance to develop amplifiers from semiconductor laser to be used as light sources. This is because of semiconductor have high gain. Laser made up with high gain
LASER-PLASMA INTARECTION With the development of the technology of laser enabled the experiments using laser pulse with a high intensity of the order 〖10〗^22 W/〖cm〗^2. So now it brings the possibility of study the parameters of plasma as well as the atoms. The study related to the laser-plasma interaction involves the self-focusing, which is a very important factor to consider. Because the intensity of such a huge order came from it and high power laser and its applications, harmonic generation,
so we can place tracks very close together, and the size of the track we use is dependent only on one thing - the color of the light we use. An optical medium typically involves some sort of laser, for laser light does not diverge, so we can pinpoint it to a specific place on the disk. By moving the laser a little bit, we can change tracks on a disk, and this movement is very small, usually less than a hairÕs width. This allows one to store an immense amount of data on one disk. The light does

manufacturing and processing techniques especially the Selective Laser Sintering (SLS), which could easily make complex geometries directly from digital CAD data. Because of my excellent performance and great enthusiasm, Prof. Yusheng Shi, a leading expert in addictive manufacturing, accepted my application to join his laboratory when I was a sophomore. I teamed up with four senior students, aiming to improve the system of selective laser sintering. We designed CAD models and made theoretic analysis
How do they know how fast we are going? Speed determination is accomplished in two basic ways. First, the least sophisticated method is dependent upon an officer's ability to guess your speed. Second, either some electronic method using radar or laser instrumentation authenticates that officer's guess. As you will see, their guesses are usually right on target. What does this mean for you? Usually a speeding ticket or if your infraction isn't a flagrant disregard for safety, a friendly warning
James T. Russell and the Invention of the Compact Disc James Russell was born in Bremerton, Washington in 1931. His first invention, at six years old, was a remote-control battleship with a storage chamber for his lunch. In 1953, he earned his Bachelor of Arts in physics and graduated from Reed College in Portland. Afterwards he went to work as a Physicist in General Electric's nearby labs in Richland, Washington. There he started many experimental instrumentation projects. He was one of
use of lasers been beneficial to medicine? The term Laser is an acronym that of Light Amplification by Simulated Emission of Electromagnetic Radiation. These lasers have many applications in many different industries around the world. However, with new uses constantly being developed lasers are proving to be extremely beneficial to the world of medicine in particular. From laser imaging and disease diagnosis to curing and treating illnesses that were not curable previously. Medical lasers have already
Laser commonly Known as Light Amplification by Stimulated Emission of Radiation. Laser is a phenomena in which a very narrow or thin beam of intense electromagnetic radiation i.e. light is emitted. Laser Beam Welding (LBW) is a welding technique or method used to join or link up pieces of metal with the help of a laser technology. The beam provides a concentrated/focused heat(infrared) source, allowing for narrow, deep, precise welds and high welding accuracy. The process is frequently/often used

Holographic Data Storage Digital technology has become the latest byword in entertainment and computers. Records and analog cassette tapes have been supplanted with Compact Discs, and now VCRs are being challenged by Digital Video Discs. Multimedia applications such as these consume enormous amounts of storage space, and are challenging the limits of today's storage devices. Many solutions are being put forth in an attempt to keep pace with the growth in demand for digital data storage. Some are evolutionary
pure coherent light source, the laser became available in 1963. The techniques of holograms are also applicable to sound, and bats may navigate by ultrasonic holography. Holographic techniques also have applications in storing dental records, detecting stresses and stains on construction and retail goods, detecting forged paintings and documents, and producing three-dimensional body scans. Holography is a method of producing three-dimensional images by means of laser light. Holography uses photographic
game? A perfect pair of soccer shoe for his game. Shoes that give them full control over the ball with a perfect accuracy that help him to soccer a goal. In my opinion, Nike did an excellent job in making their advertisement about their new T90 III laser soccer shoe. The main theme of the Nike – T90 III shoes in the advertisement, “Nike – Hit the Target,” is no matter how good you play or how famous you are in the soccer world. You still need a pair of shoe that will help in gaining control over the
Holographic Universe In autumn of 1992, one of the world's greatest contemporary physicists passed away. David Bohm, whose work inspired many people all over the world, died in London. David Bohm's contributions to science and philosophy are profound, and they have yet to be fully recognized and integrated on the grand scale. David Bohm was born on December 20, 1917, in Wilkes-Barre, Pennsylvania. Bohm was fascinated by the dazzling concepts of cosmic forces and vast expanses of space that
of three dimension objects by using interference and diffraction of light. It was invented in 1940s and develops to several types. For example, rainbow hologram is a wildly used technology on credit cards and currencies. Traditional hologram needs laser to reconstruct, but rainbow hologram only needs the white light, like sunshine. After this, people try to make hologram easier to reconstruct whereas the recording methods have not been simplified much. In the future, the digitalization may help holography
using barcode readers. Since then barcode readers are now called laser scanners. Almost every item that you purchase in a shop has a barcode on the packaging. These look like a series of thick and thin black lines. The barcode contains details about the product. It also contains a check digit, so that the computer can validate that the data has been read in correctly. The barcode details are scanned into the system by a laser scanner on the till. The check digit is calculated and compared

Laser Crowd Scanning is and amazing visual effect at most live entertainment shows, especially concerts. But, there is a bunch of safety factors that go into play before the lasers can or may be used. Some of these safety factors include, knowing where the free space is amongst the venue, understanding the angle of the beams and knowing that the safe zones aren’t amongst the areas where a person in the crowd could be in line with the beams. Before even wasting the time and effort to setup the lasers
