n electric-field poling process was established that yielded uniform periodically poled lithium niobate (PPLN) in 0.5 mm thick lithium niobate substrate. We have fabricated 50 mm long fanned as well as multigrating PPLNs having period variations from 25 µm to 32 µm. These PPLNs are required for quasi-phase-matched (QPM) optical parametric oscillator (OPO) applications. We have also configured a bench-top OPO set-up based on these PPLNs.
