摘要：

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.
