The authors observed −7.2±0.2dB quadrature squeezing at 860nm by using a subthreshold continuous-wave pumped optical parametric oscillator with a periodically poled KTiOPO4 crystal as a nonlinear optical medium. The squeezing level was measured with the phase of homodyne detection locked at the quadrature. The blue light induced infrared absorption was not observed in the experiment.
