Journal ArticleDOI
Incidence angle and polarization dependence of light diffracted by acoustic surface waves
TL;DR: In this paper, a theoretical analysis of diffracting effects produced by ASW on light beams contained on the sagittal plane of the wave is presented, produced by periodical changes of the refractive index and by corrugation of the surface in cases of x and y ‐cut crystalline quartz and y −cut LiNbO3 for both states of polarization of the incident light.
Journal ArticleDOI
Phase and amplitude relations between fundamental and second harmonic acoustic surface waves on SiO2 and LiNbO3
TL;DR: In this article, the spectral asymmetries of the light diffracted by surface waves are analyzed in order to evaluate the complex coupling coefficient in second harmonic surface wave generation and the experimental conditions are such as to keep the acoustic energy mostly confined to within fundamental and second harmonic waves.
Journal ArticleDOI
Acoustooptic interaction for most effective deflection of unguided light via acoustic surface waves.
TL;DR: The light deflection efficiencies of surface acoustic waves propagating on YZ-LiNbO(3) crystal are examined for different geometrical configurations and the optimum one is found to be the back reflection geometry, with S polarization of the impinging light beam.
Journal ArticleDOI
Image scanning through the acousto−optical effect produced by acoustic surface waves
TL;DR: In this article, the scanning of a transparency is done by letting a collimated light wave front illuminate it and be diffracted by very short pulses of ultrasonic surface waves, which give a potential number of resolved spots per second almost equal to 107.
Journal ArticleDOI
Parametric mixing of surface acoustic waves
TL;DR: In this article, a simple approximate theory for the explanation of the parametric mixing of collinear surface acoustic waves (SAW) is proposed, which considers only the transverse elastic displacement of the waves and neglects piezoelectricity.
