We present a next generation of large-aperture periodically poled Mg-doped LiNbO3 (PPMgLN) device with 10-mm thickness. Efficient optical parametric oscillation with 540 mJ output energy at 709 mJ pumping by 1.064 µm laser in 10 nanoseconds operation could be demonstrated using the 10-mm-thick PPMgLN with an inversion period of 32.2 µm at total conversion efficiency > 76%. We also confirmed that degradation effect of conversion-efficiency distribution by wedged-inversion structures, which is inevitable in current poling condition of the large-aperture PPMgLN, can be ignored in high-intensity operation.
