Query: Amplification of Electrostriction Mechanism of Photoacoustic Conversion
  in Layered Media   In this work we have performed an analysis of electrostriction mechanism of
optical to acoustical energy conversion on the interface of two materials with
low optical absorption. We compared this method of conversion with widely used
thermal conversion based on thin metal film. It was shown, that the
contribution of electrostriction mechanism is significantly lower in case of
homogeneous medium. We demonstrated the possibility to amplify the generated
acoustic signal by excitation of the guided modes, which energy is localized in
a thin (of about 200-400 nm thickness) dielectric layer. Due to high
electromagnetic field energy concentration in the structure, local values of
intensity increase by more than two order of magnitude in comparison to
intensity of incident light, that also allows to increase the amplitude of the
pressure correspondingly. Thus, in the project we propose the novel layered
dielectric structures, in which electrostriction effect occurs due to
excitation of the guided modes.
