摘要

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) approx 8ps,f velence 76 MHz). The noncritically 90 deg phase-matched ZGP SPOPO is tuned in the 3.8-5.6 (mu)m range by tuning the pump wavelength (2.25-2.5 (mu)m). As high as approx800mW of average power is emitted at 4 (mu)m.
