These incoherent photons will produce coherent photons due to stimulated emission. So photon A produced from spontaneous emission will form a number of coherent photon to itself due to stimulated emission, however photon B which is not coherent to photon A formed from spontaneous emission will produce another set of coherent photons via stimulated emissions. However the incoherence still remains. How do we form a laser then? | |
