Abstract

Pure and Er-doped ( [ Er ] crystal 2.4 × 10 20 cm 3 ) , Na Bi ( W O 4 ) 2 (NBW), Na Bi ( Mo O 4 ) 2 , and Li Bi ( Mo O 4 ) 2 crystals have been grown by the Czochralski method. The three crystal hosts have similar structural and optical properties. The noncentrosymmetric space group I 4 ¯ (No. 82) crystallographic structure has been established through 300 K single-crystal x-ray and neutron (for NBW only) diffraction. Er 3 + energy levels were determined experimentally and simulated in the S 4 symmetry through a crystal-field analysis. With this background, the large spectroscopic bandwidths observed were ascribed to the presence of two 2 b and 2 d sites for Er 3 + and to different short-range Na + and Bi 3 + distributions around both sites. The radiative properties of Er 3 + are described by the Judd–Ofelt theory achieving branching ratios and radiative lifetimes for transitions useful as laser channels. The I 13 2 4 I 15 2 4 laser channel ( λ 1.5 μ m ) shows a peak emission cross-section σ EMI ( λ 1530 nm ) 0.5 × 10 20 cm 2 and a quantum efficiency η 0.68 to 0.74. The laser emission is envisaged to be tunable by Δ λ 100 nm .
