    "abstract": "The concept of mode locking in laser is applied to a two-photon state with\nfrequency entanglement. Cavity enhanced parametric down-conversion is found to\nproduce exactly such a state. The mode-locked two-photon state exhibits a\ncomb-like correlation function. An unbalanced Hong-Ou-Mandel type\ninterferometer is used to measure the correlation function. A revival of the\ntypical interference dip is observed. We will discuss schemes for engineering\nof quantum states in time domain.",
