摘要： We propose a new two-mode thermo-and squeezing-mixed optical field, described by the new density operator ρ=(1–ef–|g|2) ega†b†efa†a|0>bb < 0|eg*ab, where|0>bb < 0|is the b-mode vacuum, efa†a represents the thermo-field, and ega†b indicates squeezing. The photon statistics for ρ is studied by virtue of the method of integration within ordered product (IWOP) of operators. Such a field can be generated when a two-mode squeezed state passes through a one-mode dissipation channel.
