A high voltage atomic force microscope has been applied for tailoring strip-like nanodomains in
RbTiOPO4 ferroelectric crystal. Highly anisotropic nanodomain propagation has been observed
owing to the difference in lattice constants along the principal axes of the RbTiOPO4 crystal.
Studying the influence of the applied high voltage, and tip velocity on the domain strips has allowed
us to fabricate fine nanodomain gratings, which is useful for backward-propagating
quasi-phase-matched frequency conversion. 2003 American Institute of Physics.

The recently developed electrical poling method has en-
abled us to fabricate engineered domain superlattices peri-
odic, quasiperiodic, aperiodic, multiperiodic, etc. in ferro-
electric FE crystals in the micrometer scale. Such structures
have allowed us to generate coherent light at any wavelength
within the FE crystal transparency, and to develop tunable
laser sources in a wide spectral region where compact and
efficient lasers are unavailable.1,2
