In three-mode Fock space we construct a new tripartite entangled state |α, γ⟩ θλ which makes up a new quantum mechanical representation. The state |α, γ⟩ θλ can be generated by using the set-up composed of an asymmetric beam splitter and a parametric down-conversion amplifier. We then show how to use |α, γ⟩ θλ to find new squeezing operator and new squeezed state.
