The History Lasers

  • Electromagnetic radiation

    Electromagnetic radiation
    Max Plank published work in 1900 that provided the understanding that light is a form of electromagnetic radiation. Without this understanding the laser would not have been invented.

    History of Lasers

    This is a timeline on the history of lasers for my QUEST program.
  • Stimulated Emission

    Stimulated Emission
    Albert Einstein first theorized about the process which makes lasers possible called "Stimulated Emission."
  • Confirmed

    Rudolph W Landenburg confirmed existence of stimulated emission and negative absorption.
  • Start of stimulated emission

    Several different engineers were working towards the harnessing of energy using the principal of stimulated emission.
  • The Maser

    The Maser
    Charles Townes and Arthur Schawlow invented the maser (Microwave Amplification by Stimulated Emission of Radiation), using ammonia gas and microwave radiation - the maser was invented before the (optical) laser. The technology is very close but does not use a visible light.
  • The Laser

    The Laser
    Gordon Gould, a doctoral student under Townes, uses the term ‘laser’, theorising tht light could be used to excite atoms into making a coherent light beam.
  • The Maser for Space

    The Maser for Space
    Charles Townes and Arthur Schawlow was granted a patent for the maser. The maser was used to amplify radio signals and as an ultra-sensitive detector for space research.
  • The Ruby Laser

    The Ruby Laser
    Theodore Maiman invented the ruby laser considered to be the first successful optical laser or light laser.
  • Laser Surgery

    Laser Surgery
    Laser used for first time in surgery to destroy retinal tumor.
  • The Semiconductor Laser

    The Semiconductor Laser
    Robert Hall created a revolutionary type of laser, the semiconductor laser, that still used in many electrical appliances and communication systems today.
  • The Carbon Dioxide laser

    The Carbon Dioxide laser
    The carbon dioxide laser was invented by Kumar Patel.
  • Barcode Scanner

    Barcode Scanner
    First supermarket barcode scanner developed by Bernard Silver
  • First laser printer

    IBM creates the first laser printer: the IBM 3800
  • Laser Disc Player

    Laser Disc Player
    First laser disc player made by Phillips. But hight cost is barrier to success.
  • Laser Eye Surgery

    Laser Eye Surgery
    John D Myers created the first commercial laser eye surgery device and method
  • Short-sightedness

    First laser surgery to correct short-sightedness.
  • Mini-lasers

    Alferov and Kroemer were given the prize for their development within the field of semiconductor physics, where they had studied the type of substances that was first used to build semiconductor lasers, that is, the kind of miniature lasers that today have become the cheapest, lightest and smallest.
  • Destroying brain cancer

    Destroying brain cancer
    French neurosurgeons use fibre-optic laser and keyhole surgery to destroy brain cancer.
  • Lasers today

    Lasers today
    The CD player, laser writer, laser pointer and the bar code reader the cashier at the supermarket uses, are all based on the discovery of lasers. And yes guys, no laser shooting.
