It is shown that photon-excitation state defined by |α, k⟩<sub>q</sub> = â<sub>q</sub><sup>†k</sup>|α⟩<sub>q</sub> (k=1,2,3...) up to a normalization constant can be produced in nonlinear processes in q-nonlinear cavities. The mathematical and quantum statistical properties of this state are studied in detail. We show that this state, along with the number states absented in it, forms a complete set. We also show by numerical method that this state exhibits quantum-squeezing for some values of |α| and always reveals quantum-antibunching effect.
