Abstract:
Nd-doped gadolinium aluminium tetraborate Nd x Gd 1- x Al 3 (BO 3 ) 4 (NGAB) crystals have been grown by flux method, with large sizes and good optical quality as well as different Nd 3+ ion densities of 0 to 10 at.% in the lattice structure. These crystals belong to the trigonal system with point group 32, conforming space group R32. The unit cell constants are a =0.9305(8) and c =0.7248(1) nm, V =0.5436 nm 3 for a Nd 3+ content of 10 at.%. When Judd–Ofelt (JO) theory of parity-forbidden electric-dipole transitions of rare earth ions on non-centrosymmetric sites is applied to NGAB, it results in a good fit on absorption of the crystal. The three intensity parameters Ω t are fitted as 1.559×10 -20 , 1.751×10 -20 and 2.395×10 -20 cm 2 at t =2, 4 and 6 respectively, with a root-mean square deviation of 9.35×10 -22 cm 2 . The spectral parameters of NGAB crystal have indicated that it is a promising candidate of self-frequency doubling crystals.
