A new Yb-doped niobate, 5at%Yb :GdNbO4, has been grown by Czochralski method. The structures of Yb: GdNbO4were determined by Retvield refine to their X-ray powder diffraction. Their diffuse reflection spectra, photo-luminescence spectra and lifetime at room temperature were measured and the corresponding energy level transitions were assigned, respectively. Then spectroscopic parameters of Yb: GdNbO4 were calculated and compared with Yb: YNbO4, Yb: GdTaO4 and Yb:YAG. Results indicated that Yb: GdNbO4 crystal is advantageous for tunable and ultrafast pulse laser output and will be a new promising Yb laser material pumed by LD.
