    , directional output of monochromatic (single. wavelength) light. This can be understood when one thinks of two light sources; the florescent light that is. probably above your desk right now and the laser pointer you got as a give-away at a tradeshow. Whereas. both sources emit light, the florescent bulb does
  • You Never Forget Your First Laser
    every day in ways we may not even recognize. We tend to use things without thinking about them. Has it ever occurred to you that every time you listen to a CD or point with a laser pointer, you are holding the discovery of a Nobel Prize Laureate in Physics, in your hand? Well, if you haven't, you're

    IF you take a torch and shine it at a distant wall it will illuminate a very large area. On the other hand, a modest laser pointer will deliver light energy over only a very limited area. One device employs a large reflector with incoherent light, while the other has a minimal reflector and highly
  • Wired 9.08: Beam On
    The wavelength of a laser beam depends on the type of atom or compound used in the chip. Ordinary laser pointers have a chip containing aluminum gallium arsenide phosphide, and emit a red beam at a wavelength of 670 nanometers. The reactive substance in a conventional pump laser is gallium indium
