我们制作并表征了周期性极化铌酸锂单片光学参量振荡器（OPO）和发生器。紧凑的单片器件是琐碎的对准和操作，并提供广泛可调，几乎衍射限制，稳定的输出脉冲。在3.5 ns 1.064 mum脉冲泵浦下，器件获得了低阈值和高转换效率。此外，单片OPO器件通过非共线相位匹配的晶体旋转表现出宽调谐特性。测量并解释了非共线相位匹配几何结构中的带宽增宽效应。
We fabricated and characterized periodically poled lithium niobate monolithic optical parametric oscillators (OPO's) and generators. The compact monolithic devices were trivial to align and operate and provided widely tunable, nearly diffraction-limited, stable output pulses. Low thresholds and high conversion efficiencies were obtained when the devices were pumped with 3.5-ns 1.064-mum pulses. In addition, the monolithic OPO devices exhibited broad tuning by crystal rotation through noncollinear phase matching. The bandwidth-broadening effects exhibited in the noncollinear phase-matching geometry were measured and explained.
