Acoustooptical Interaction in Optically Active Mediaasonic waves are generated as shear rotational waves propagating in a rod (corresponding to a nonlinear medium) of circular cross-section while optical beams are impinging side walls of the rod. The optical beams are coherent and linearly polarized and can be thought as the sum of left-hand and right-hand polarized components (Fig. 1).

Study of the Dislocation Dynamics by Ultrasonic Cyclic Bias Stress Experimentscle of the applied stress. The shapes of these curves and their evolution are characteristic for each mechanism controlling the dislocation motion. For this reason, the shapes of these curves have been called the “signatures” of the mechanisms controlling the dislocation dynamics.

Thin Film and Layer Characterizationpace including liquid-solid boundaries. Special emphasis on theoretical and experimental work on leaky Rayleigh waves will be given. The thin layer substrate problem will be followed by the same structure loaded with water. Both Lamb waves and leaky Lamb waves will be introduced and application of t

Determination of Linear and Nonlinear Parameters of Thin Layersgreat importance on the generation and detection of high frequency bulk and surface acoustic waves, in applications including acoustic microscopy and acousto-optic Bragg cells. Thin film overlays are widely used for improving the acoustic propagation characteristics and the transducer performance in
