摘　　要：本文采用提拉法生长了Cr，Yb，Ho：YAGG可调谐激光晶体，并从理论上讨论了热应力、提拉速度、晶体转速和降温速率等因素对晶体开裂的影响，最后给出了掺铬、镱和钬钇铝镓石榴石激光晶体生长的最佳工艺条件：温度梯度为0．5℃／mm，提拉速度1-2mm／h，晶体转速20-40r／min，冷却速率不超过20℃／h。Cr, Yb, Ho： YAGG tunable laser crystal was grown by CZ method. The crystal cracking was studied and the results shown that crystal cracking is related to the pulling rate, rates of rotation and cooling. The optimum growth parameters of Cr, Yb, Ho： YAGG tunable laser crystal were given： temperature gradient, 0.5℃/mm ; pulling rate, 1-2mm/h ; rotation rate, 20-40r/min ; cooling rate, less than 20℃/h .
