Abstract

We report the first successful growth of Nd-doped Sc x Y1−x VO4 crystals (0<x≤1) by the Czochralski technique. For a successful synthesis, the upper limit of the Sc concentration in the YVO4 melt was found to be below 10 at%. The spectroscopic characterization of an Nd-doped laser crystal, i.e., Nd:Sc0.011Y1.003V0.986O3.986, is discussed. Diode pumping of a c-cut crystal yielded an output power of 1.1 W at a wavelength of 1.06 μm with a slope efficiency of 43%: The slope efficiency of an a-cut crystal was 37%.
