Abstract ： The Judd-Ofelt theory was applied to optical-absorption transitions in an Nd3+ -doped polymer optical fiber to obtain intensity parameters (Ω2 = 0.83 x 10-20 cm2 , Ω4 = 1.64 x 10-20 cm2 , Ω6 = 4.04 x 10-20 cm2 ) the radiative lifetime (371 μs) and quantum efficiency (0.73) of the 4 G5/2 level, from which we found that the transition probability from 4 G5/2 to 4 I9/2 (Aij = 1995.7 s-1 ) is higher than others. Thus, in the polymer system, the traditional four-level laser system for the Nd3+ was substituted by a three-level system. Furthermore, we have calculate the emission cross section(σe ij =2.45 x 10-21 cm2 ), and solved the differential equations of the single-pass gain. In comparsion with the case of the inorganic optical fiber, an increased saturated intensity is observed.
