Large, doped crystal ingots are grown in a Stockbarger furnace from a melt of an alkali metal or alkaline earth metal salt using very slow oscillation (1 - 2 cycles per minute) of the ingot through a small arc of 5 DEG -20 DEG to produce an ingot having a more even distribution of dopant and an absence of open boundaries between macrocrystals within the ingot.
