  • Laser Light
    566 words
    Light in the Modern World Since the beginning of time, mankind has made use of light, from simple things such as planting crops in areas of abundant light to things as well thought out as Stonehenge on the Salisbury plains. Not being content with having to rely on natural light from the sun and stars alone, we have created our own light. Our first method was fire, in such things as candles and oil lamps. More recently, however, we have relied mainly on electricity to provide us with artificial l...

  • Laser Light
    1,037 words
    The Laser Before we can learn about the laser we need to know a little bit about light (since that is what a laser is made of). Light from our sun, or from an electric bulb, is called white light. It is really a mixture of all the different colours of light. The colours range from violet, indigo, and blue, to green, yellow, orange, and red. These make up the visible part of the electromagnetic spectrum. Light is made up of particles, called PHOTONS, which travel in waves. The difference in the c...
  • Use Of The Lasers
    1,303 words
    When most people see a laser beam they are amazed by its unique physical properties. Laser light is so unique from other light because it is coherent; unlike ordinary light, which travels in all directions, laser light travels in a straight beam. The word laser is an acronym for Light Amplification by Stimulated Emission of Radiation. The history of the laser is very interesting. Lasers have changed immensely since they were first invented. Before the laser was invented, Charles Townes developed...
  • Gas And Semiconductor A Solid State Lasers
    885 words
    Lasers and Their Uses We have all at some point in our lives used or seen someone use a laser. They are used in compact disc players for stereos or computers, laser surgery, laser printers, holography, cutting and boring metals, communication, bar-code scanners, etc. Over the past three decades' lasers have become a tool used daily by many people and they have become very useful in scientific research. As you can see lasers are a very useful and important tool which is why I have chosen this top...
  • White Light Reflection Hologram
    2,181 words
    Holography While working to improve the resolution of an electron microscope, a brilliant man named Dennis Gabor had developed a theory on Holography. This dates back to the year of 1947. Dennis Gabor is a British / Hungarian scientist who created the word Holography from Greek terms. He used the word holds, meaning "whole", and gramma, meaning "message". Gabor characterized his work as "an experiment in serendipity" that was begun too soon. The next decade brought about frustration in Holograph...
  • Types Of Holograms
    2,291 words
    I have chosen to do my MIS paper on holograms. I have chosen this topic because it is a technology that has been around for sometime now, but has become increasingly more popular in recent years. Holograms are now found in virtually all types of products. These products consist of currencies, checks, stock certificates, credit cards, passports, ID cards, computer software, audio / visual tapes and CD ROMs, aircraft, software, electrical / electronic appliances, building materials, food, pharmace...
  • Lasers In Cancer Surgery
    882 words
    The word ^aEURoelaser^aEUR is the combination of the first letters of the statement ^aEURoelight amplification by stimulated emission of radiation^aEUR (Hecht, p: 1). As an explanation of this statement, it can be said that laser is a device that creates and amplifies a narrow intense beam of consistent light. Laser light, has a specific wavelength and is focused in a narrow beam. This type of high-intensity light contains a lot of energy. Laser is an important technology because it has contribu...
