    "abstract": "We observe -9.01$\\pm$0.14 dB of squeezing and +15.12$\\pm$0.14 dB of\nantisqueezing with a local oscillator phase locked in homodyne measurement. In\nreference [1], two main factors are pointed out which degrade the observed\nsqueezing level: phase fluctuation in homodyne measurement and intracavity\nlosses of an optical parametric oscillator for squeezing. We have improved the\nphase stability of homodyne measurement and have reduced the intracavity\nlosses. We measure pump power dependences of the squeezing and antisqueezing\nlevels, which show good agreement with theoretical calculations taking account\nof the phase fluctuation.",
