报道了锁模激光泵浦参量放大器产生的压缩脉冲序列的双光子符合计数测量。通过测量同一锁模脉冲内和不同锁模脉冲间两种符合的比值，可以确定零延时下的强度关联函数。对强度关联函数g（2）进行了单模分析，解释了实验结果。由于探测成对光子的几何问题，理论和实验之间的差异进行了讨论。
A two-photon coincidence counting measurement is reported of a squeezed pulse train from a parametric amplifier pumped by a mode-locked laser. The intensity correlation function at zero time delay can be determined by measuring the ratio of two types of the coincidences, the one within the same mode-locked pulse and the one among different pulses. A single mode analysis of the intensity correlation functiong(2) is made to explain the experimental results. A discrepancy between the theory and the experiments due to a geometrical problem of detecting the paired photons is discussed.
