首次使用坩埚下降法生长了蓝光掊频晶体铌酸钾锂K3Li2-xNb5＋xO15＋2x（0＜x＜0．5），探讨了该晶体的最佳生长条件，包括组份选择、原料处理、炉温控制、温场设计等，成功地生长出直径10mm、长度25mm的透明KLN晶体．
Potassium lithium niobate crystal K3Li2-xNb5+x015+2x (0< x <0.5) for blue second-harmonicgeneration applications was grown by the modified Bridgman technique for the first time. Thegrowth conditions, including the selection of starting compositions, preparation of the startingmaterials, design of the temperature distribution and control of the furnace temperature, werediscussed. A transparant KLN crystal with 10mm in diameter and 25mm in length was grownsuccessfully.
