本文综述了周期极化铌酸锂体材料准相位匹配光学参量振荡器的研究进展。使用电场极化过程中，我们可以可靠地制造0.5毫米厚的晶体均匀的域结构超过15毫米的长度。周期性极化材料保留了单畴LiNbO 3的低损耗和大功率处理特性，准相位匹配允许与最高值非线性系数da（33）的非临界相位匹配。用1.064 μ m脉冲Nd：YAG激光器泵浦的光学参量振荡器，在1.4-4 μ m波长范围内工作，可通过温度调谐或准相位匹配周期调谐。我们已经表明，振荡阈值低至0.012毫焦耳的Q开关泵浦激光器的谐振振荡器附近的1.96 μ m直接泵浦的商业连续二极管激光器在978 nm。(C)1995年美国光学学会
We review progress in quasi-phase-matched optical parametric oscillators in bulk periodically poled LiNbO3. Using the electric-field poling process, we can reliably fabricate 0.5-mm-thick crystals with uniform domain structures over a 15-mm length. Periodically poled material retains the low-loss and bulk power handling properties of single-domain LiNbO3, and quasi phase matching permits noncritical phase matching with da(33), the highest-valued nonlinear coefficient. Optical parametric oscillators pumped by 1.064-mu m pulsed Nd:YAG lasers have been operated over the wavelength range 1.4-4 mu m with tuning by temperature or by quasi-phase-matched period. We have shown an oscillation threshold as low as 0.012 mJ with a Q-switched pump laser resonant oscillator near 1.96 mu m pumped directly with a commercial cw diode laser at 978 nm.
