Frequency doubling in periodically poled RbTiOAsO ₄

Abstract

A flux grown RbTiOAsO4 crystal was periodically poled by applying a high voltage pulse on patterned liquid electrodes. It was used for first order quasi-phasematched blue light second harmonic generation. To our knowledge this is the first demonstration of successful periodic poling of a flux grown crystal from the KTiOPO4 family.
