Ultrahigh-resolution and polarization-sensitive optical coherence tomography was used to examine the domain boundary of periodically poled lithium niobate (PPLN). A 3D image of antiparallel domains in PPLN crystal was characterized with a sub-micron axial resolution.
The fabrication of periodic poled Lithium Tantalate single crystal fibers by the laser heated pedestal growth method were achieved with in-situ monitoring of transient poling current. The whole cross section of the fiber is poled through as seen from the confocal measurement.

The fabrication of a periodic poled Lithium Tantalate single crystal fibers were firstly achieved in-situ via the laser heated pedestal growth method. The spectrum of second harmonic generation was characterized.

A novel self-cascaded first-order SHG and third-order SFG in ZnO:PPLN crystal fiber for the generation of tunable blue/green light source is demonstrated. About 700 muW output power at 477. lnm was measured with a tuning range of 35nm.
