Large-aperture periodically poled Mg-doped LiNbO3 device using X-axis Czochralski-grown MgLN crystal was proposed to avoid a laser-beam distortion problem. Availability of periodic poling in 5-mm-thick MgLN and compatibility of wavelength-conversion characteristics in QPM-OPO were evaluated by comparing with conventional arrangement using Z-axis-grown crystal.
