    "abstract": "We show that three-level atoms excited by two cavity modes in a $\\Lambda$\nconfiguration close to electromagnetically induced transparency can produce\nstrongly squeezed bright beams or correlated beams which can be used for\nquantum non demolition measurements. The input intensity is the experimental\n\"knob\" for tuning the system into a squeezer or a quantum non demolition\ndevice. The quantum correlations become ideal at a critical point characterized\nby the appearance of a switching behavior in the mean fields intensities. Our\npredictions, based on a realistic fully quantum 3-level model including cavity\nlosses and spontaneous emission, allow direct comparison with future\nexperiments.",
