The Kerr effect in atomic vapor may be regarded as the power saturation of the susceptibility. Hence the saturable Kerr effect is intimately tied to the standard Kerr effect. Here, we calculate the saturable Kerr effect without parameters using a two-level system and compare to experiment. An asymmetry between red and blue detuning led us to consider a model with one ground state and three excited states.
