Abstract
A new crystal of Yb-doped gadolinium niobate, 5at.% Yb:GdNbO4, is grown by Czochralski method for the first time. The structure of Yb:GdNbO4 is determined by Rietveld refinement to the X-ray powder diffraction data and it belongs to the monoclinic space group of I2/a. With the center of 955nm, the FWHM of absorption spectra is 57nm and the absorption cross section is calculated to be 0.97×10−20cm2. Spectral parameters are calculated with absorption spectrum. In emission spectra, the strongest peak is at 1001nm and the FWHM is 49nm. In comparison with corresponding emission cross section of Yb:YSO and Yb:GSO, Yb:GdNbO4 exhibits a relatively larger emission cross section. In addition, a maximal output power of 270mW is obtained and the slope efficiency is 7.5%.
