The exact analytic expressions for the photon statistics distribution, the squeezing degree S and the second order degree of coherence g(2) of light field are obtained by using the master equation for the density operator of light field and applying the generation-function method. The evolution of these quantities with the scale-time τ are discussed. It is shown that the squeezing degree S, which is gradually reduced in two-photon absorption process, may still exhibit the squeezing feature. Moreover, the process is favorable to the existence and the enhancement of photon antibunching effect and photon sub-poissonian statistics feature, but the oscillatory characteristics of photon statistics distribution disappear rapidly after having been preserved in a short time.
