摘要：

We show that a ring four-wave mixing oscillator operating above threshold can generate twin photon beams. The experiment is done with sodium vapour and the output power of the oscillator is of the order of a few milliwatts. The noise power measured on the intensity difference between the two generated beams exhibits a quantum noise reduction of 10%. © 1990 IOP Publishing Ltd.
