Abstract

Summary form only given. According to Feynman, quantum mechanics teaches us that interference occurs when the relevant amplitudes become indistinguishable. In the case of first-order and second-order interference (order by "intensity"), the relevant amplitudes are one-photon and two-photon amplitudes, respectively. We report a quantum interference experiment in which the relevant amplitudes are associated with temporally well separated laser pulses. Both first- and second-order interference are observed under certain different conditions. The experimental setup is shown where a BBO crystal is pumped by two short UV laser pulses.
