An Yb:YVO4 single crysal with good optical quality and large size has been
grown by the Czochralski method. We have discussed the growth shape of Yb:Y
VO4 single crystal which is composed of {100} and {101} simple forms. The d
ata of thermal expansion and specific heat of the crystal have been measure
d. The thermal expansion coefficients along a- and c-axis directions art: a
lpha(1) = 1.5 x 10(-6)/K and alpha(3) = 8.2 x 10(-6)/K, respectively. The s
pecific heat is 30.4 cal/mol K at 320 K. The absorption and fluorescence sp
ectra have been measured.
