Growth and spectral properties of the Nd3+:Ca2Nb2O7

Abstract This paper reports the growth and spectroscopic characterization of Nd 3+ :Ca 2 Nb 2 O 7 crystal. Nd 3+ :Ca 2 Nb 2 O 7 crystal with dimension up to ∅15 × 40 mm 3 have been grown by Czochralski method. The absorption cross-section at 798 nm and the emission cross-sections σ em at 1068 nm are 2.95 × 10 −20 cm 2 and 6.204 × 10 −20 cm 2 , respectively. The fluorescence lifetime is 103 μs at 300 K.
