【Abstract】 Tetragonal zircon-type YP_xV_1-xO₄ （x≤0.15） single crystal has been pulled using the Czochraski method from YVO₄-YPO₄ solid-phase system. The analytic result for the concentration of P element indicates that YP_xV_1-xO₄ single crystal can be grown with stoichiometric compositions. The crystal lattice parameters, refractive index and the optical damage threshold were tested. The transparency of crystal is close to 80% in wavelength 400-3?000?nm and absorption peak is not exist. In addition, the fluorescence emission of crystal is low. The test results illustrate that YP_xV_1-xO₄ （x≤0.15） single crystal can be used as laser host crystal of rare earth ions.更多还原
