Rare earth vanadate (REVO4) crystals for laser applications

 
 
Simultaneous growth of two items of  Nd-YVO4 crystal (EFG technique). Square section, 3 mm side each item.  As-grown Nd-doped (1 at.%) and Yb-doped (10 at. %) YVO4 single crystals.

 
 
YVO4 crystal (9 mm in diameter, 100 mm in length) grown by  EFG (edge-defined-film-fed growth) technique. Photo was made after annealing process. As-grown Yb-doped YVO4 (10 at. %) single crystals. 4 items were grown simulteneously. 
 
As grown YVO4 crystal (EFG technique) (80 mm in length, 10 mm in section size. Square shape !!!) Same crystal after annealing.
