ResumoThe thermal properties, absorption spectra and Raman spectra of Yb:YAG crystal with different Yb3+ ion concentrations are reported. The results show that the ytterbium concentration influences the properties of Yb:YAG. At high doping level, the thermal conductivity decreases and the absorption peak centered at about 940 nm shifts to shorter wavelength. The Raman spectra reveal that the lattice vibrational modes of highly doped Yb:YAG is different from that of low-doped Yb:YAG crystal. The effect of Yb3+ concentration on the properties is regarded as the result of lattice deformation. The influence of Yb concentration on laser is also analyzed.
