摘要：

Transparent and homogeneous Nd:GdVO4 crystals have been obtained by the Czochralski method. The room temperature absorption spectra has been measured and compared with that of 0.2 mol.L-1NdCl3 solution. The spectral strength parameters: Omega(2) = 12.629 x 10(- 20) cm(2), Omega(4) = 4.828 x 10(-20) cm(2), Omega(6) = 8.425 x 10(-20) cm(2) of Nd3+ ion were fitted according to the Judd - Ofelt theory. The radiative transition probabilities A(J,F), oscillator strengths P-J,P-F, radiative lifetime tau and the branching ratio beta(F) were also calculated. A highest output power of up to 14.3 W at 1.06 mum was observed with a 4 nun thick Nd: GdVO4 crystal sample when pumped by a 26 W cw laser diode array. The light - light conversion efficiency was 55%, with an average slope efficiency of 63%.
