Paper Abstract

Nd:Ca1-xYxF2+x(x=0%,2%,5%,10%) crystals were grown by Temperature gradient technique. The emission spectrum and absorption spectrum were tested. The emission cross section, emission bandwidth and absorption cross section were calculated. The influence of codoping ions on the spectral performance was compared and analyzed. These crystals have better spectral parameters than Nd:CaF2 crystals. By increasing the concentration of Y3+, spectral properties could be optimized. Among these crystals, the crystal with x=10% has the longest fluorescence lifetime (283.5 μs). The crystal with x=5% has the largest emission cross section(2.90× 10-20 cm2) and the largest absorption cross section(2.18× 10-20 cm2).
