In this paper, the effects of instantaneous state of Er doped fiber laser are studied. The expressions in dicating the photon population density perturbations with time in Er doped fiber laser are given. The fluctuation functions of photon population density under pumping perturbations are solved at the first order approximation. Furthermore, the properties of the white noise and the resonance effects are discussed in detail.
