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.
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。这种紧凑的单片器件易于对准和操作，并能提供广泛可调谐、接近衍射极限的稳定输出脉冲。当用3.5纳秒的1.064微米脉冲泵浦这些器件时，可获得低阈值和高转换效率。此外，单片OPO器件通过晶体旋转实现非共线相位匹配，从而展现出宽调谐特性。我们测量并解释了在非共线相位匹配几何结构中表现出的带宽展宽效应。
