Note that the squeezing levels shown in this paper are for the quadrature observables defined by X̂ = ∫∞-∞dtΨ0(t)X̂(t). They can be directly evaluated with the initial squeezed vacua right after the OPO, using a following expression;2〈X̂2〉≡1−2γTζ0.z(z+3)(z+1)(z+2)2. Here, z=PPth is normalized pump power where P is pump power and Pth is an oscillation threshold of the OPO.
