We report generation of squeezed vacuum in sideband modes of continuous-wave light at 946nm using a periodically poled KTiOPO4 crystal in an optical parametric oscillator. At the pump power of 250mW, we observe the squeezing level of -5.6±0.1dB and the anti-squeezing level of +12.7 ± 0.1dB. The pump power dependence of the observed squeezing/anti-squeezing levels agrees with theoretically calculated values when phase fluctuation of locking is taken into account.
