    "abstract": "We report a two-photon interference effect, in which the entangled photon\npairs are generated from two laser pulses well-separated in time. In a single\npump pulse case, interference effects did not occur in our experimental scheme.\nHowever, by introducing a second pump pulse delayed in time, quantum\ninterference was then observed. The visibility of the interference fringes\nshows dependence on the delay time between two laser pulses. The results are\nexplained in terms of indistinguishability of biphoton amplitudes which\noriginated from two temporally separated laser pulses.",
