摘　　要：用传统降温法生长了大尺寸KDP单晶，生长速度一般在1～2mm／d，周期长，风险大。本文采用“点籽晶”快速生长法多次成功生长出了200mm级的大尺寸KDP单晶，晶体生长速度达到20mm／d，晶体生长正常。同时，摇摆曲线表明快速生长的晶体有着很好的结构完整性。By using the traditional temperature-reduction method, the growth rate of KDP crystal is 1-2 mm/d. The growth cycle of large scale KDP crystals is so long that the chance to get perfect crystal is little. In the present work ,200 mm grade KDP crystals was grown at the growth rate of 20 mm/d by the ＂point-seed＂ rapid growth method. The growth of KDP is normal, and the rocking curve show that the large scale KDP crystal grown by ＂point-seed＂ rapid growth method is with high structural integrality.
