document: Phase control of higher-order squeezing of a quantum field In a recent experiment -LSB- Phys . Rev. Lett . 88 -LRB- 2002 -RRB- 023601 -RSB- , phase-dependent photon statistics in a c.w. system has been observed in the mixing of a coherent field with a two-photon source . Their system has the advantage over other atomic transition-based fluorescent systems . In this paper , we examine further the squeezing properties of higher-order quantum fluctuations in one of the quadrature components of the combined field in this system . We demonstrate that efficient and lasting higher-order squeezing effects could be observed with proper choice of the relative phase between the pump and coherent fields . This nonclassical feature is attributed to a constructive two-photon interference . Relationship between the second - and higher-order squeezing of the field is discussed
