Abstract—The investigation of structural perfection and laser properties of a new class of mixed vanadates
Y_xSc_1–xVO₄:Nd³⁺ was carried out in this work. The research of the structural perfection of the crystals was
carried out by applying the X-ray diffractometer. It was shown that the Y_xSc_1–xVO₄:Nd³⁺ crystals have a good
structural perfection. The lasing experiment shows that the maximal CW output power of 2 W was achieved
upon 5.8 W pumping. The maximal slope efficiency of 41.5% was obtained along the [100] crystallographic
direction for the -polarization.
