The high optical quality crystal of Er:GYSGG with a size up to Φ 30×100 mm was first successfully grown by the Czochralski method. The lattice parameter of Er:GYSGG is 12.5073Å and the Sellmeier coefficients were fitted to be A=3.78681, B=0.01579 μm2, C=2.72454 μm2, D=0.08204 (μm2)-1, respectively. The absorption and fluorescence spectra of Er:GYSGG before and after 100 Mrad gamma-ray radiation have no obviously changed, and the irradiated crystal has a shorter lifetime of lower energy level than the crystal with no radiation. All the results suggest that Er:GYSGG is a promising material for 2.7-3μm wavelength laser gaining and its excellent ability of radiation resistance indicated that it can be used in radiant environments such as outer space
