a tellurium dioxide crystal is presented. The all-optical acousto-optic effect describes the combination of laser generated ultrasound with acousto-optic interaction. Laser generated ultrasound spectra are analyzed for tellurium dioxide using a 266 nm and a 1064 nm pulsed source, and used to characterize the acoustooptic interaction. The interaction is shown to be dominated by longitudinal acoustic waves. Results are given for a simple device structure which obtains nearly a thirty percent diffraction efficiency. Future trends are also discussed. The authors would like to thank GE Global Research for their support of this work.
