I’ll use this knowledge to simulate a working laser. We will learn how LASERs relies on Stimulated absorption, Spontaneous emission, and most importantly: Stimulated Emission- This last type interacts with an excited atom, causing it to relax/deexcite. It will send out a photon with the same phase, frequency, polarization and direction. We exploit this principle in a optical cavity, with the atom as a gain medium. \n
