Abstract

PURPOSE: To mass-produce homogeneous single crystals of lead molybdate as a medium for ultrasonic light modulation in a high yield by inclining the pulling direction of each seed crystal by a specified angle from the a axis of the crystal when the seed crystal is pulled up from a melt to grow a single crystal.
CONSTITUTION: Each single crystal of lead molybdate as a seed crystal is dipped in a melt of lead molybdate and slowly pulled up to grow a large-sized single crystal. At this time, the seed crystal 1 is cut out so that the ABEF face and the opposite CDGH face parallel to the ABEF face are inclined by 1W9° to the a axis of the crystal. When this single crystal is pulled up from the melt of lead molybdate, the pulling direction coincides with the direction 1 of the side CG of the crystal, and the occurrence of a striationlike subgrain boundary in a grown single crystal can be inhibited. Thus, high quality single crystals of lead molybdate can be manufactured in a high yield.
