- Y. Gao and M.F. DeCamp "Generation of acoustic pulses from a photo-acoustic transducer measured by time-resolved x-ray diffraction" Applied Physics Letters 100 191903 (2012) The work studied the generation of picosecond acoustic pulses generated by ultrafast optical excitation of a photo-acoustic transducer using time-resolved x-ray diffraction. The resulting pump-probe spectra reveal that the spatiotemporal structure of the acoustic pulse is bipolar with acoustic wavevectors up to inverse of the film thickness.
