Please teach me: if stimulate photons have energy different from the difference of two energy levels of atom then what is happened?What is coefficent of the stimulate emission in this case?

I'm uncertain which type of photons you are referring to. Stimulated (the photon produced) or stimulating the incident photon)?

I mean the incident photon that striking on excited atoms.

The probability of stimulated emission falls very rapidly as the energy of the photon moves away from the energy difference between the two energy levels, but I confess I don't know the mathematical details.

How do we know that?But I know Eisntein coefficents B=B' when energy of photon equal the difference of energy levels of atom.
