The Fizzz of Stimulated Emission


Let's consider our electrons in an excited state in the conduction band.

Let's suppose that we send photons:

  • these photons stimulate the electrons in the conduction band

  • the electrons fall back into the valence band
  • Photons emitted by stimulated emission have the same energy as the incident photons and are in step with each other: this type of light is called coherent light.
