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?

Stimulated emission is a process in which an excited atom or molecule releases energy in the form of a photon, resulting in the production of multiple photons with the same energy, phase, and direction as the original photon.
Spontaneous emission occurs randomly and without any external influence, while stimulated emission requires an external photon to trigger the release of additional photons.
In laser technology, stimulated emission is the fundamental process that allows for the generation of coherent and monochromatic light, making it useful in various applications such as cutting, welding, and medical procedures.
Stimulated emission can only occur in a system with a population inversion, which is when a larger number of particles are in an excited state compared to the ground state. This creates a chain reaction of stimulated emissions, resulting in amplification of light.
Some common examples of stimulated emission include laser pointers, barcode scanners, and DVD players. Additionally, stimulated emission is a natural process that occurs in fireflies, where the chemical reaction in their bodies produces light through stimulated emission.
