The single crystal growth conditions and spectroscopic characterization of Ni-doped MgGa2O4 with inverse-spinel structure crystal family are described. Single crystals of this material have been grown by floating zone method. Ni-doped MgGa2O4 single crystals have broadband fluorescence in the 1100-1600 nm wavelength range, 1.6 ms room temperature lifetime, 56% quantum efficiency and 1.05 x 10(-21) cm(2) stimulated emission cross section at the emission peak. This new material is very promising for tunable laser applications covering the important optical communication and eye safe wavelength region. (C) 2009 Elsevier B.V. All rights reserved.
