摘要：
We report the fabrication of a 12-mu m-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-mu m-period grating at an elevated temperature of 174 degrees C. The resultant green second-harmonic output exhibited fundamental-spatial-mode characteristics at a 4.3% W-1 conversion efficiency. (C) 1999 Optical Society of America.
