We theoretically analyze a pump–probe experiment to detect the optical Stark effect on impurity‐bound excitons taking the quantization of the pump field into account. A density matrix approach allows the calculation of the probe absorption spectra with high accuracy. For bound excitons with low inhomogeneous broadening of several tens of μeV, the photon statistics of the pump field has a considerable influence on the lineshape of the Stark‐shifted resonance. The effect should be clearly observable for broad photon number distributions and low pump detuning.
