The lasing transition 4 F 3/2 ® 4 I 11/2 for Nd 3+ doped phosphate glass centered around 1.05 – 1.07mm is referred as hypersensitive transition. The radiative properties such as effective linewidth (D l eff ), radiative transition probability (A R ), branching ratio (b R ), radiative lifetime (t R ), quantum efficiency (h) and stimulated emission cross section have been obtained for several phosphate and fluorophosphate glass contained Nd 3+ . The experimental and calculated oscillator strength were used to analysis Judd-Ofelt parameters (W 2 , W 4 and W 6 ) also to predict the quality of factor c. The phosphate glass material with the approximately 69P 2 O5-15Na 2 O-15K 2 O-1Nd 2 O 3 composition at 4 F 3/2 ® 4 I 11/2 transition is suitable for laser medium. The enhanced radiative transition probability as well as branching ratio and stimulated emission cross section in this glass are 3694 s -1 , 52% and 8.67 x10 -20 cm 2 respectively. As in commercial laser, the magnitudes of the emission cross section in this study achieved in the range 4.0-5.0 x 10 -20 cm 2 .
