LASERS  

DÉFINITION

  • LASERS (Light Amplification by Stimulated Emission of Radiation): Any of several devices that emit highly amplified and coherent radiation of one or more discrete frequencies. One of the most common lasers makes use of atoms in a metastable energy state that, as they decay to a lower energy level, stimulate others to decay, resulting in a cascade of emitted radiation.
