| 摘 要： | 对周期性极化高掺镁铌酸锂倍频过程进行了准相位匹配倍频理论研究。在室温下通过外加电场极化法，用较低的极化开关电场～5．5kV／mm，在厚为1mm、长为10mm、宽为10mm的掺镁铌酸锂基片上成功地制备了周期为5．8～7．3pm(间隔0．3pm)的一阶准相位匹配倍频周期性极化光学微结构。将温度控制在70℃左右，以波长为1．060μm的Nd：YAG激光为基频光源，对所研制的光学微结构样品进行倍频通光实验验证。当入射基频光为920mW时，可以获得约15mW的532nm准连续倍频蓝光输出．其归一化转换效率高达1．77％／W。

| Abstract: | The double-frequency process based on periodically poled heavily doped MgO∶LiNbO3 is theoretically researched. A first order quasi-phase-matching periodically poled optical micro-structure doped MgO∶LiNbO3 for second harmonic generation with 5.8～7.3 μm period(interval of 0.3 μm), 10 mm length, 10 mm width and 1 mm thickness has been successfully fabricated by applying an external field at room temperature and under ～5.5 kV/mm of the lower switching field. Controlling temperature at about 70 ℃，the experiment on the manufactured optical micro-structure using Nd∶YAG laser with wavelength of 1.064 μm as fundamental frequency is carried to validate the double frequency. About 15 mW 532 nm of quasi-continuous-wave double-frequency blue light output is obtained which is pumped by 920 mW of the fundamental power, corresponding to 1.77 %/W normalized conversion efficiency. |
