| 摘 要： | Thermal properties of pure KY(WO4)2 and K(Y1-xYbx)(WO4)2(x=0.098,0.196,0.294) crystals were investigated.The specific heat and thermal diffusivity of crystals were calculated at a range of 50～300 ℃.The calculated result shows that the specific heat and thermal diffusivity of K(Y1-xYbx)(WO4)2(x=0.098,0.196,0.294) crystals were slightly affected by the Yb3+ concentration.The thermal expansion coefficient of K(Y0.804Yb0.196)(WO4)2 crystals along x,y and z axes were determined to be 13.51,4.474 and 16.60×10-6 K-1,respectively.These results suggest the K(Y1-xYbx)(WO4)2(x=0.098,0.196,0.294) crystal as a laser crystal of low-middle power.

| Abstract: | Thermal properties of pure KY(WO_4)_2 and K(Y_(l-x)Yb_x)(WO_4)_2 (x=0.098,0.196,0.294) crystals were investigated.The specific heat and thermal diffusivity of crystals were calculated at a range of 50～300 ℃.The calculated result shows that the specific heat and thermal diffusivity of K(Y_(1-x)Yb_x)(WO_4)_2 (x=0.098,0.196,0.294) crystals were slightly affected by the Yb~(3+)concentration.The thermal expansion coefficient of K(Y_(0.804)Yb_(0.196))(WO_4)_2 crystals along x,y and z axes were determined to be 13.51,4.474 and 16.60 x 10~(-6) K~(-1),respectively.These results suggest the K(Y_(1-x)Yb_x)(WO_4)_2(x=0.098,0.196,0.294) crystal as a laser crystal of low-middle power. |
