。As the raw material 4 for growth, a natural crystal raw stone (rath force) crushed into an appropriate size was used. Next, a seed crystal 6 is placed on the growth raw material 4 via a seed crystal support frame 5. As the zero seed crystal, for example, a Z plate of natural or artificial optical grade quartz is used. In order to avoid causing defects in the single crystal to be grown, a seed crystal with few internal inclusions, dislocations, etc. is required. The raw material for growth 4 and the seed crystal 6 are arranged in this way, and a breadboard 7 is placed between them via the seed crystal support frame 5 as well. Also, add a coloring additive to the inside of the pressure vessel. The pressure vessel having such a structure is filled with a NazCO3 aqueous solution as a medium at a filling rate such that a predetermined pressure is obtained at a predetermined temperature.
