掺稀土四硼酸铝钆晶体及其生长方法
摘要：
本发明涉及自倍频激光非线性光学晶体材料掺稀土四硼酸铝钆及其熔盐法生长工艺。本发明晶体分子组成为RexGd1-xAl3(BO3)4，0≤x≤0.18，Re为稀土元素或过渡金属，该晶体具有很强的非线性光学性质及良好的激光性质，适合LD泵浦倍频及自倍频激光器应用。将RGAB、K2Mo3O10、Re2O3和B2O3按1∶(2.0～3.0)∶(0.1～1.2)∶(0.1～1.2)的摩尔比称量，然后按熔盐法工艺生长晶体。以本法生长晶体质量好，工艺稳定，重复率高，设备简单，成本低，操作简便，生长后处理容易。
摘要（英）：

The present invention relates to an self-frequency-doubling laser non-linear optical crystal material mxied with rare earth doped aluminium-gadolinium tetraborate and its growing process of molten salt method. Said invented crystal molecular composition is RexGd1-xAl3(BO3)4, O is not more than X, and the X is not more than 0.18, and Re is rare earth element or trasition metal. Said crystal possesses strong non-linear optical property and good laser property, and is applicable to LD pumping frequency-doubling and automatic frequency-doubling laser. The RGAB, K2Mo3O10, Re2O3 and B2O3 are weighed according to the mole ratio of 1:(2.0-3.0):(0.1-1.2):(0.1-1.2), then are used for growing crystal by using moltensalt process. Said invented process is simple in equipment, low in cost, easy to operate and its crystal quality is high.
