                                         Information @ a Glance
  • A laser is an electronic-optical device that emits coherent light radiation. The term "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation.
  • A typical laser emits light in a narrow, low-divergence beam, with a narrow wavelength spectrum ("monochromatic" light).
  • In this respect, laser light is in sharp contrast with such light sources as the incandescent light bulb, which emits incoherent light over a wide area and over a wide spectrum of wavelengths, and differs from LED light which is not coherent.
  • The word light in this phrase is used in the broader sense, referring to electromagnetic radiation of any frequency, not just that in the visible spectrum. Hence there are infrared lasers, ultraviolet lasers, X-ray lasers, etc.
  • The microwave equivalent of the laser, the maser, was developed first, devices that emit microwave and radio frequencies are usually called masers.
  • In the continuous wave (CW) mode of operation, the output of a laser is relatively consistent with respect to time. The population inversion required for lasing is continually maintained by a steady pump source.
  • The first application of lasers visible in the daily lives of the general population was the supermarket barcode scanner.
  • 'High Powered' green handheld 125milliwatt lasers have recently been used in attacks on aircraft pilots landing at Australian airports. The risk is that if the laser hit the pilots eyes it could cause temporary blindness at a critical point in the flight.
  • Lasers that produce pulses can also be characterized based on the peak power of each pulse. The peak power of a pulsed laser is many orders of magnitude greater than its average power. The average output power is always less than the power consumed.
  • Dye lasers use an organic dye as the gain medium. The wide gain spectrum of available dyes allows these lasers to be highly tunable, or to produce very short-duration pulses.
  • Photonic crystal lasers are lasers based on nano-structures that provide the mode confinement and the density of optical states (DOS) structure required for the feedback to take place.
