Abstract: In this paper, we report the research on the effect of the "immersion" technology adopted in the Nd:YAP crystal growth process by the Czochrolski method on the quality of the crystal. We find that the "immersion" technology can improve the crystal quality.

Key words: crystal material, application of a new method, determining crystal quality, Positron annihilation technique
