Abstract
We report the fabrication of a 12-mu m-thick periodically poled LiNbO3 plan ar waveguide buried in LiTaO3 by direct bonding of precision-polished surfa ces. Frequency doubling of the 1064-nm output of a cw diode-pumped Nd:YAG l aser 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-har monic output exhibited fundamental-spatial-mode characteristics at a 4.3% W -1 conversion efficiency. (C) 1999 Optical Society of America.
