In this work we have performed an analysis of an 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 the widely used thermal conversion based on thin metal film. It was shown that the contribution of the electrostriction mechanism is significantly lower in the case of the homogeneous medium. We demonstrated the possibility to amplify the generated acoustic signal by…

TLDR
A theoretical model describing this process shows that the pump induces the phase modulation of the probe pulse leading to its compression by about 20% and the variation of the delay between two SPP pulses up to 15 fs for the incident fluence of the pump of 1.5 mJ∙cm⁻².
