what is the source of the first photon in the laser ?
i understand there is a burst of light or electricity that excites up the medium , but what is the source of the first photon ? is it the light source or is it one atom of the medium itself releasing photon as it gets de-excited * if that's even a word * ?
also i would really like to know in layman terms why does an excited atom release a photon of the same wavelength of a photon that passes near it without actually interacting with it or absorbing it
