We demonstrate electro-optic spectral tuning in a pulsed periodically poled LiNbO 3 (PPLN) optical parametric oscillator (OPO) in ns regime. A 3-cm-long LiNbO 3 crystal is segmented in three equal sections; the outer sections are periodically poled. The center segment is of single domain whose refra
