Abstract :
An Al-phosphate glass containing Nd3+in concentrations ranging from 3 \\times 10^{20} to 2.7 \\times 10^{21} ions/cm3has been prepared and investigated spectroscopically. Different ways of measuring the4F3/24I9/2emission cross sections yield values between 1.96 \\times 10^{-20} and 2.7 \\times 10^{-20} cm2. At the highest concentration the decay time is 50 μs, while the radiative lifetime is estimated to be \\geq 446 \\mu s. Lasing experiments were performed by pumping thin platelets of glass coaxially with a dye laser. Cross sections, losses, and differential efficiencies are derived from these experiments. The status of high concentration glasses versus stoichiometric Nd compounds is reviewed.
