We have successfully launched and detected guided acoustic interface waves in both simulated domain wall structures and actual differentially poled ceramics. A heterodyne laser probe has been used to measure the acoustic field distributions associated with these waves. Remanent polarization and strain measurements have also been performed on differentially poled ceramic specimens. Composite resonators and interface waveguides are being characterized by laser probe techniques. Author
