| Abstract: | The polarized absorption spectra, infrared fluorescence spectra, upconversion visible fluorescence spectra, and fluorescence decay curve of orientated Nd3+:KGd(WO4)2 crystal were measured at room-temperature. Some important spectroscopic parameters were investigated in detail in the framework of the Judd-Ofelt theory and the Fuchtbauer-Ladenburg formula. The effect of the crystal structure on the spectroscopic properties of the Nd3+ ions was analyzed. The relation among the spectroscopic parameters and the laser performances of the Nd3+:KGd(WO4)2 crystal was discussed. |
