At any stage the excited state atoms can release some of the energy and return to a lower-energy orbital.The energy released in the form of photons has a very specific wavelength that is dependent on the level of energy or excitation the electron when the photon is released.
Two identical atoms with electrons in identical states will release photons with identical wavelengths. This forms the basis for laser light.
