Abstract

Quantum-correlated twin beams were generated from a triply resonant optical parametric oscillator with an a -cut KTP crystal pumped by a frequency-doubled diode laser. A total output of 5.1 mW was obtained in the classical–nonclassical light-conversion system driven by a 50-mW diode laser at 1080 nm. A quantum-noise reduction of 4.3 dB (63%) in the intensity difference between the twin beams was successfully observed at the detection frequency of 3 MHz.
