Just like absorption, the chance of stimulated emission is proportional on the intensity of the light bathing the atom. Einstein mathematically expressed the statistical nature from the three probable radiative transition routes (spontaneous emission, stimulated emission, and absorption) With all the so-called Einstein coefficients and quantified the relations between the a few processes. One of several early successes of quantum mechanics was the proper prediction from the numerical values of the Einstein coefficients to the hydrogen atom.
The talk has raged for generations amongst the giants of the physics community concerning the nature of light, namely whether it is a particle or an electromagnetic wave.
