  • Abstract
    We report the measurement of the amplification cross section σ21of the Nd3+ion in the POCl3-SnCl4-(H2O) system by three different methods. The first is based on the simultaneous measurement of the variation of fluorescence and Q -spoiled laser emission. The second is purely spectroscopic. The third is based on the measurement of k12at several temperatures. The two last methods give similar results. The most probable value is \\sigma _{21} = 8.5 \\times 10^{-20} cm2. An explanation for the lowest value \\sim 6 \\times 10^{-20} cm2found with the first method is given.
