Three langasite family crystals of Sr 3 Ga 2 Ge 4 O 14 (SGG), Ca 3 NbGa 3 Si 2 O 14 (CNGS), and Sr 3 NbGa 3 Si 2 O 14 (SNGS) were successfully grown by the modified Bridgman method. Among them, SGG crystals up to 2 inches were obtained with the multi‐crucible industrial Bridgman furnace; SNGS crystal grown in any orientation direction other than along a ‐axis was realized. Commercially availability SGG boules and the advantage in SNGS crystal indicated that the modified Bridgman technique is a prospective method to realize the mass‐production of the langasite‐type crystals.
