    "abstract": "We observed -7.2 dB quadrature squeezing at 860 nm by using a sub-threshold\ncontinuous-wave pumped optical parametric oscillator with a periodically-poled\nKTiOPO4 crystal as a nonlinear optical medium. The squeezing level was measured\nwith the phase of homodyne detection locked at the quadrature. The blue light\ninduced infrared absorption was not observed in the experiment.",
