Using the amplification transfer function of type Ⅰ BBO crystal, the theoretical study of spatial properties of the optical parametric fluorescence generated by homochromatic signal and polychromatic signal in optical parametric amplification is investigated, The numerical simulation results demonstrate that when the homochromatic signal is injected into optical parametric amplifier, the fluorescence signal is first emitted in a cone and then in a ring while centering on the pump wave direction.
