Abstract
Nd : YVO 4 single crystal with good optical quality and large dimension has been grown by Czochralski method. The synthesizing of Nd : YVO 4 polycrystalline material and some problems of single crystal growth have been studied. We have developed the equilibrium shape of Nd : YVO 4 single crystal which is composed of {1 0 0} and {1 0 1} simple forms. The effective segregation coefficients k eff of elements have been measured and k eff of Nd element is about 0.63. The lasing at 1.06 μm has been demonstrated pumped by a 3 W laser diode (LD), and the light–light conversion efficiency is up to 50%.
