We report on the experimental operation of a picosecond, singly resonant, synchronously pumped optical parametric oscillator (SPOPO) based on a ZnGeP(2) (ZGP) crystal. The ZGP SPOPO is pumped with the idler radiation from a diffraction-grating-tuned periodically poled lithium niobate SPOPO emitting a continuous picosecond pulse train (Delta tau approximately 8 ps, f=76 MHz). The noncritically 90 degree phase-matched ZGP SPOPO is tuned in the 3.8-5.6 microm range by tuning the pump wavelength (2.25-2.5 microm). As high as approximately 800 mW of average power is emitted at 4 microm.
我们报告了一种基于 ZnGeP(2) (ZGP) 晶体的皮秒、单共振、同步泵浦光参量振荡器 (SPOPO) 的实验运行情况。ZGP SPOPO 用从衍射光栅调谐的周期性极化铌酸锂 SPOPO 发射的闲频辐射泵浦，产生连续的皮秒脉冲串（Delta tau 约为 8 ps，f=76 MHz）。非临界 90 度相位匹配的 ZGP SPOPO 通过调谐泵浦波长（2.25-2.5 微米）在 3.8-5.6 微米范围内调谐。在 4 微米处，最高可达约 800 mW 的平均功率。
