Abstract

We present a full-wafer fabrication process for periodically poled lithium niobate with a 6.5µm domain period. Samples that were 53  mm long and 0.5  mm thick were obtained with this process for single-pass cw 1064-nm Nd:YAG second-harmonic generation. These samples exhibited 78% of the ideal nonlinear coefficient, had a measured conversion efficiency of 8.5%/W in the low-power limit, and produced 2.7  W of cw 532-nm output with 6.5  W of cw input, which corresponds to 42% power conversion efficiency.
