A probed optical lattice is modelled as a driven anharmonic oscillator with noise. For specific values of the probe intensity and detuning, atoms are forced in bistable solutions. The friction and fluctuations that arise from laser cooling, determine the equilibrium between these two modes of vibration. The distribution determines the absorption spectrum and the transient emission spectrum that is emitted by the optical lattice after the probe has been switched off.
