Melinda Rose and Hank Hogan

In 2020, the laser will celebrate its 60th anniversary. Here Photonics Media presents a timeline of some of the more notable scientific accomplishments related to light amplification by stimulated emission of radiation (laser). An interactive version of the laser timeline is also available, as well as a primer on laser basics detailing how lasers work. A trip through the light fantastic The laser would not have been possible without an understanding that light is a form of electromagnetic radiation. Max Planck received the Nobel Prize in physics in 1918 for his discovery of...Read full article

    maser
    An acronym for microwave amplification by stimulated emission of radiation. Predecessor to the laser, the maser or 'microwave laser' was the first device to produce coherent electromagnetic waves, and was done at microwave frequencies through amplification by stimulated emission. A laser (light amplification by stimulated emission of radiation) is a maser that works over a broader range of higher frequency photons in the ultraviolet and visible portion of the electromagnetic spectrum.
