摘要：

Nd-doped gadolinium vanadate Nd:GdVO4 crystal with large sizes and good optical quality has been grown by Czochralski method. When the Judd-Ofelt theory of parity-forbidden electric-dipole transitions of rare earth ions on non-centrosymmetric sites is applied to the Nd:GdVO4, it results in a good fit on the absorption of the crystal. The spectral parameters of Nd:GdVO4 crystal have indicated that it is an excellent candidate laser material. The three intensity parameters Omega (t) are fitted as 12.629 x 10(-20), 4.828 x 10(-20) and 8.425 x 10(-20) cm(2) at t = 2, 4 and 6, respectively. In laser experiment, the highest output power of up to 14.3 W at 1.06 mum has been achieved with a 4 mm thick Nd:GdVO4 crystal sample when it is pumped by a 26 W cw fiber-coupled laser-diode array. The light-light conversion efficiency is 55%, and the average slope efficiency is 62%. (C) 2001 Published by Elsevier Science B.V.
