    "abstract": "We report the observation of non-classical quantum correlations of continuous\nlight variables from a novel type of source. It is a frequency non-degenerate\noptical parametric oscillator below threshold, where signal and idler fields\nare separated by 740MHz corresponding to two free spectrum ranges of the\nparametric oscillator cavity. The degree of entanglement observed, - 3.8 dB, is\nthe highest to-date for a narrowband tunable source suitable for atomic quantum\nmemory and other applications in atomic physics. Finally we use the latter to\nvisualize the Einstein-Podolsky-Rosen paradox.",
