Fabrication and characterization of 5-mm-thick periodically poled MgO:LiNbO/sub 3/ device

Fabrication of 5 mm-thick periodically poled MgO-doped LiNbO/sub 3/ device with 32.1 /spl mu/m period was demonstrated by temperature-elevated field poling technique. The periodic-structure quality was evaluated by second-harmonic generation of 954 nm using d/sub 31/-coefficient.
