Generation and Detection of Optoacoustic Waves in Liquids by the Photothermal Lens Technique
The mode-mismatched photothermal lens (PTL) technique can be used to investigate transient acoustic waves induced by pulsed laser excitation in liquids at the nanosecond time scale [1]–[3]. The recent advances in the theoretical description of optoacoustic waves have enabled the PTL technique to be used as a quantitative method for material characterization [2], [3]. The method allows quantitative determination of a complete set of physical properties, such as thermal diffusivity, optical absorption coefficient, sound speed, and piezo-optic coefficient [1].
