摘要：

We demonstrate electro-optic spectral tuning in a pulsed periodically poled LiNbO3 (PPLN) optical parametric oscillator (OPO) in ns regime. A 3-cm-long LiNbO3 crystal is segmented in three equal sections; the outer sections are periodically poled. The center segment is of single domain whose refractive index is changed by electro-optic effect. Applying voltage from 0 to -5000 V, the OPO signal and idler waves are tuned from 1.932 to 1.912 mum and 2.368 to 2.40 mum, respectively. The signal and idler waves obtained are difference-frequency-mixed in a 10 mm long AgGaS2 crystal to produce mid-IR tunable from similar to10.5 to similar to9.4 mum, which matches the tuning range of a CO2 laser.
