    A maser is a device that produces coherent electromagnetic waves (microwaves), through amplification by stimulated emission The term is an acronym for microwave amplification by stimulated emission of radiation
  • What is a MASER? - Stanford University
    Basically, a man-made MASER is a device that sets up a series of atoms or molecules and excites them to generate the chain reaction, or amplification, of photons Metastable emission states make MASERs and LASERs possible
  • Maser | Microwave Amplification Applications | Britannica

  • What Is a Maser? - Spiegato
    A maser is a type of technology similar to a laser Where a laser is a directed energy tool or weapon based on light amplification by the stimulated emission of radiation, a maser instead uses microwave amplification, or electromagnetic fields instead of coherent light beams, to produce similar results
