Paper Abstract

In this paper experimental results of He-Ne laser light diffraction by ultrasound in a liquid waveguide are pre-sented. The 45 MHz ultrasound (also known as layer waves) in the liquid waveguide, which consists of water sandwiched between two parallel plates of LiNbO3 and fused quartz, is generated by interdigital transducers at one end of the LiNbO, plate. The diffracted light is used to obtain inforMation about the properties of these layer waves, such as the velocity dispersion for different mode of propagation. This optical probing also enables one to directly observe the evanescent ultrasound in the guiding solids and measure the decay parameter. Possible applications in the field of integrated optics and signal processing are discussed.
