Abstract

In this paper we present a comprehensive description of the pump-probe holographic arrangement and data processing procedure optimized for reconstruction of long smooth strain wave patterns in transparent solids. The approach was tested on detection of nonlinear strain waves generated in a uniform PMMA bar by initial shock pulses of different energies. Phase images representing these waves in the bulk of the waveguide are demonstrated. The strain wave parameters and evolution were shown to be substantially dependent on the initial shock pulse amplitude.
