Thermally coupled interfacial acoustic waves observed in transient surface-grating measurements

We report the observation of interfacial acoustic waves in the gas above opaque condensed media excited by pulsed laser radiation in transient surface-grating experiments. They differ from previously described interfacial waves in the coupling between the media: Stoneley, Scholte and others describe...
