    "abstract": "Quantum-correlated twin beams were generated from a triply resonant optical\nparametric oscillator with an a-cut KTP crystal pumped by a frequency-doubled\ndiode laser. A total output of 5.1 mW was obtained in the\nclassical-to-nonclassical-light conversion system driven by a 50-mW diode laser\nat 1080 nm. Quantum noise reduction of 4.3 dB (63%) in the intensity difference\nbetween the twin beams was successfully observed at the detection frequency of\n3 MHz.",
