| 摘 要： | 我们通过测定MgO在同成分LiNbO3中的有效分凝系数、相位匹配温度与MgO浓度之间的关系,找到了使Mg:LiNbO3晶体的相位匹配温度达到最高的掺MgO配方,并克服了Mg:LiNbO3晶体在高掺杂生长时易出现生长条纹和脱溶等问题,从而生长出了抗光折变能力强,光学均匀性良好的Mg:LiNbO3晶体。用于连续泵浦Nd:YAG声-光调Q腔内倍频时,获得了平均功率最高达2瓦的二次谐波输出。关键词： |

| Abstract: | By determining the relations between the effective distribution coefficient of MgO in the congruent LiNbO3 and the phase-matching temperature and the concentration of MgO, chemical composition which makes the Mg :LiNbO3 to get the highest phase-matching temperature has been found. The problems frequently encountered in heavily doped Mg:LiNbO3 crystal growth, such as growth striations and precipitation etc, have been resolved.The Mg:LiNbO3 crystals with high resistance to light-induced refractive index changes and good optical quality have been grown. Using the crystals for frequency doubling of a continuously pumped acousto-optical Q-switch Nd :YAG laser, second harmonic output with the highest avarage power of 2W have been obtained. |
