A non-classical state of the radiation field, which we call the excited two-photon coherent state, is defined by m-times applying the photon creation operator on Yuen's two-photon coherent state . Its squeezing and sub-Poissonian character are demonstrated. Its generalized quasiprobability distribution functions in the representation are obtained and compared with those of the state and the Agarwal - Tara excited coherent state . It is observed that the exhibits remarkable non-classical properties differing from those of and .
