Answer:there won't be enough atoms that are excited around to undergo stimulated emmision
Explanation:
Stimulated Emission is the process used in laser operations to produce photons.
In stimulated emission a passer-by photon stimulates the atom to emit a photon, identical to the passer-by photon, immediately. The con to this is that the same passer-by photon could instead get absorbed by a de-excited atom. Therefore, aside of atom excitation we need to use witty ways to insure that there are more excited atoms that could use the passer-by photon for stimulated emission than there are de-excited atoms.
Photons produced by this stimulation have the same wavelength which enables efficiency as all photons are emitted into the same node.
Scientific knowledge is built as people come up with hypotheses and theories, repeatedly check them against observations of the natural world and continue to refine those explanations based on new ideas and observations.
