Abstract: We have generated noncollinear quasi-phase-matched second
harmonic wave in an RbTiOPO4 crystal that was poled using the high-
voltage atomic force microscope (HV-AFM). To the best of our knowledge,
this is the first systematic nonlinear frequency conversion study of samples
produced by the HV-AFM method. The short poling period of 1.18 µm
enabled us to observe second harmonic generation at very large angles with
respect to the fundamental wave. The setup was used to optically explore
the homogeneity of the poled area. The measurements are in a reasonable
agreement with an analytic calculations.
