Description/Abstract
We report the fabrication of a 12-µm-thick periodically poled LiNbO3 planar waveguide buried in LiTaO3 by direct bonding of precision-polished surfaces. Frequency doubling of the 1064-nm output of a cw diode-pumped Nd:YAG laser was performed in a 5.5-mm-long device with a 6.50-µm-period grating at an elevated temperature of 174 °C. The resultant green second-harmonic output exhibited fundamental-spatial-mode characteristics at a 4.3% %/W conversion efficiency.
