Abstract
The Nd3+ multicenter distribution in a Ca3Sc2Ge3O12 garnet laser crystal has been analyzed by low temperature site-selective laser spectroscopy. Two nonequivalent Nd3+ centers have been identified and characterized in this host lattice. The effect of codoping the crystal with MgO on the Nd3+ center distribution has also been investigated, since this codoping enables considerable enhancement of the doping levels of these crystals. Three different centers were observed in the codoped crystals, together with a reduction of inhomogeneous emission broadening. The nature of the optical centers present in both cases is discussed by considering the charge compensation mechanisms involved in accommodation of Nd3+ ions.
