Resumo
The radiation hardness of neodymium-doped gadolinium vanadate crystal (Nd:GdVO4) has been investigated. Crystal with sizes of 4×4×8 mm doped to a level of 0.5% Nd3+ and (for comparison) undoped GdVO4 crystal were γ-irradiated by a 60Co source to an absorbed dose of about 106 to 107 rad. The photoinduced absorption spectra of the crystals have been studied. Intense lasing with a differential efficiency up to about 25% was obtained in an irradiated Nd:GdVO4 crystal. It is shown that irradiation of a crystal up to a dose of 107 rad does not reduce significantly its laser efficiency.
