| abstract | (57) [Abstract] [Purpose] It is possible to use a large-diameter raw material rod, or to speed up the feeding speed of the raw material rod to produce a large single crystal using yttrium vanadate as a mother crystal, and to reduce growth fringes. . [Structure] A melting zone is formed between a seed rod and a raw material rod containing at least yttrium and vanadium by converging irradiation of infrared rays, and the melting zone is relatively moved in the raw material rod to sequentially form single crystals. In producing a single crystal having yttrium vanadate as a mother crystal, at least a portion where the raw material rod and the seed crystal are in contact, containing oxygen, If the composition ratio of vanadium and yttrium is V / Y, A black substance having a composition in which V / Y is 0.8 ≦ V / Y ≦ 1.25 and absorbing in a wavelength band of 0.4 μm or more and 1.3 μm or less. The raw material rod may be a sintered body obtained by firing at least yttrium oxide and vanadium oxide, or a single crystal having yttrium vanadate as a mother crystal. |
