Abstract
A method to periodically pole conductive ferroelectric materials has b een developed. With this method we have fabricated high quality domain inverted crystals of flux grown KTiOPO4 suitable for efficient quasi- phase matched frequency conversion. Samples have been evaluated by sec ond harmonic generation and normalized conversion efficiencies up to 6 .9%/W cm(2) have been obtained. (C) 1997 American Institute of Physics .
