We observed two-photon phase superresolution in an unbalanced Michelson interferometer with classical Gaussian laser pulses. Our work is a time-reversed version of a two-photon interference experiment using an unbalanced Michelson interferometer. A measured interferogram exhibits two-photon phase superresolution with a high visibility of 97.9% +/- 0.4%. Its coherence length is about 22 times longer than that of the input laser pulses. It is a classical analog to the large difference between the one-and two-photon coherence lengths of entangled photon pairs.
