We will extend Duan's simple model to analyze the mixing of the 4fN-15d-configuration with the 4fN-states. We consider the explicit static coupling and traditional dynamic coupling, and fit the parameters according to the absorption spectrum in LiYF4 : Nd3+. The parameters obtained are T32=-28i·10-7, T52=-1151i·10-7, A232=192i·10-12 cm, A452=i·10-12 cm, A672=54i·10-12 cm and A676=-680i·10-12 cm. Compared to the experimental measurements, the present model yields better results than whose obtained from the Judd--Ofelt theory.
