“…The photothermal mirror (TM) spectrometry detects the deformation of the illuminated surface by analyzing the focusing or defocusing of the reflected probe beam in the far field region [8][9][10][11][12]. TM measures a convoluted signal arising from the wavefront distortion caused by the probed surface of the sample in addition to the phase shift created by heat-coupling in the fluid surrounding the sample.…”

“…This method has been recently introduced under pulsed Gaussian laser excitation for the measurement of thermal diffusivity and thermo-optical properties of semi-transparent and opaque solids [8,9] and for the detection of thermoelastic waves launched by a localized heat deposition [13][14][15]. This method has also been used to detect surface displacements induced by radiation pressure at air-liquids interfaces [11,12].…”

We propose a combined pump-probe optical method to investigate heat diffusion properties of solids. We demonstrate single-shot simultaneous laser-induced thermoelastic surface displacement of metals detected by concurrent measurements using photothermal mirror and interferometry. Both methods probe the surface displacement by analyzing the wavefront distortions of the probe beams reflected from the surface of the sample. Thermoelastic properties are retrieved by transient analysis in combination with numerical description of the thermoelastic displacement and temperature rise in the sample and in the surrounding air. This technique presents a capability for material characterization that can be extended to experiments for quantitative surface mapping.

“…12,13 Using a slightly different experimental approach, this method was also employed to measure the surface deformation induced by radiation pressure at air-liquid interfaces induced by continuous and pulsed laser excitation. 19,20 Here we show, for pulsed laser excitation in metals, that the launched elastic waves propagate on the surface and within the solids generating convoluted photothermal mirror signals following the thermo-mechanical properties of the sample. The elastic waves are predicted by the numerical solution of the thermoelastic equation and have properties closely related to the familiar elastic waves created by an isotropic point-expansion source on the surface of solids.…”

We investigate the thermoelastic waves launched by a localized heat deposition. Pulsed laser excitation is used to generate mechanical perturbations in metals that are detected using the photothermal mirror method. This method detects the wavefront distortion of the probe beam reflected from the perturbed sample surface. Nanometer scale expansion of the material is induced just under the irradiated surface releasing transient thermoelastic waves of much smaller amplitudes on the surface. Numerical predictions and the experimental results are in a good agreement and represent both the thermal diffusion of the large amplitude, long-lasting outward bulge, and the released elastic waves.

“…In ultrasonic research and associated applications, it is essential for interpreting measurements and understanding the underlying physical mechanisms. Due to recent strides in fundamental research, particularly regarding the measuring of light-pressure-induced ultrasound [1,2] and the so-called Abraham-Minkowski controversy [3,4,5,6,7,8,9,10,11], laser ultrasound modeling is gaining a new momentum and a novel aspect in its applicability.…”

Laser-induced ultrasonic waveform derivation and transition from a point to a homogeneous illumination of a plate

et al. 2017

Ultrasound modeling, being an established practice, is used to study the fundamentals of light-matter interactions. Although much has been published on the matter, pressure and thermal expansion induction mechanisms in laser ultrasonics have rarely been combined, as they should, in a single ultrasonic source while the effects of its size variation have only been shown to a limited extent. In the paper, we unite these light-matter interaction mechanisms, with inclusion of lateral optical forces, into a single laser-stimulated source as it is observed in nature. With a laser pulse as a manipulable source, we simulate the multifaceted workings of light-matter interactions by exposing the distinct transients originating from different source localities as generated by different induction mechanisms. We also present a transition of simulated ultrasonic waveforms in the epicentral point on the surface of a solid plate opposite from the source while it is expanded from a point to a quasi-limitless extent for pressure and thermal expansion generation regimes. The model utilizes geometric probability theory together with Huygens' superposition principle and temporal convolutions to construct the desired waveforms out of individual Green's functions. We show how the ultrasound generation regimes stem out of a single source and how its size together with energy and momentum transfers during the light-matter interactions affect the induced ultrasonic transients.
