The growth and characterization of Cr,Nd:Y3Al5O12 (YAG) crystal are reported. By improving the synthesis and sintering processes of polycrystalline materials, as well as the temperature gradient and annealing atmosphere, a high quality crystal with size of ϕ30 mm × 110 mm is obtained by using the Czochralski technique. After measuring the concentrations of dopant Cr3+ and Nd3+ within the different...
