“…It has found a plethora of applications in solid‐state physics for nanoscale imaging and is now attracting growing attention in cellular imaging, as was summarized in a very recent review in Ref. . After first being demonstrated on plant cells , TDBS has since been extensively used to study the viscoelasticity of a variety of mammalian cells , originating from different tissues.…”

Advances in microscopy with new visualization possibilities often bring dramatic progress to our understanding of the intriguing cellular machinery. Picosecond optoacoustic micro‐spectroscopy is an optical technique based on ultrafast pump‐probe generation and detection of hypersound on time durations of picoseconds and length scales of nanometers. It is experiencing a renaissance as a versatile imaging tool for cell biology research after a plethora of applications in solid‐state physics. In this emerging context, this work reports on a dual‐probe architecture to carry out real‐time parallel detection of the hypersound propagation inside a cell that is cultured on a metallic substrate, and of the hypersound reflection at the metal/cell adhesion interface. Using this optoacoustic modality, several biophysical properties of the cell can be measured in a noncontact and label‐free manner. Its abilities are demonstrated with the multiple imaging of a mitotic macrophage‐like cell in a single run experiment.

“…It was shown in our recent work that the technique of time-domain Brillouin scattering (TDBS) [19] permits 3Dscanning of transparent samples with sub-μm axial resolution, in addition to the micrometric lateral resolution [18,20,21]. In the present paper, we applied this capability of the TDBS technique to obtain 3D distributions of elastic inhomogeneities in polycrystalline samples of the fcc argon compressed in a DAC [20] and to pitch the extreme n·V L values closely approaching the n·V L 111 and n·V L 100 up to the highest pressure of our work of 64 GPa (Fig.…”

Single-crystal elastic moduli C i j , shear modulus G, and Zener anisotropic ratio A of solid argon having the face-centered cubic (fcc) structure were determined at high pressures between 12 and 64 GPa using a combination of experimental and theoretical approaches. The experimental data, namely, the maximal and minimal values of the product of the longitudinal sound velocity and refractive index n·V L , were obtained from the 3D scanning of elastic inhomogeneities in compressed samples of argon using the technique of time-domain Brillouin scattering. These inhomogeneities, caused by elastic anisotropy of solid argon, were revealed to be about twice as strong as those reported in the earlier experiments using classical Brillouin light scattering (BLS). To derive the V L values, we used the refractive index obtained here from ab initio calculations which also permitted us to rule out any contribution to the amplitude of the observed elastic inhomogeneities of the hexagonal close-packed phase of argon, proposed to coexist with the fcc phase at high pressures. From the measured C i j (P), we derived pressure dependence of shear modulus of the fcc argon G H (P) using the Voigt-Reuss-Hill approximation and found a very good agreement with the earlier G(P) obtained from shear sound velocities in the classical BLS measurements. Our results agree very well with the earlier predictions based on a relatively simple many-body model employing the Buckingham pair potential. Finally, our measurements show a much weaker change of the Cauchy discrepancy (C 12 − C 44 − 2P) of the fcc argon with pressure than reported in all earlier experimental and theoretical works.

“…In this technique, a pump laser pulse generates a picosecond coherent acoustic pulse (CAP) of nanometers-length in the material, while a time-delayed probe laser pulse exhibits additional scattering by this photo-generated CAP. Detecting this additionally scattered light via heterodyning [16][17][18][19] provides information on the acoustical (sound velocity), optical (refractive index), and acousto-optical (photoelastic constant) parameters of the material in the current position of the CAP [18,20,21]. In materials that are transparent for probe light and are spatially homogeneous, the detected signal of the CAP-induced probe reflectivity variation has a sinusoidal form with respect to the increasing time-delay of the probe laser pulse relative to the pump laser pulse.…”

“…From the BF images in Figure 3, it is additionally important to notice that the BF appears to vary as a function of time for a given lateral position. Indeed, TDBS is a known modality for depth-profiling and imaging [20,21,[37][38][39][40]. The distribution of the BFs as a function of the time delay between the probe and pump pulses can be transformed in the depth distributions of the BF.…”

Picosecond laser ultrasonics is an experimental technique for the generation and detection of ultrashort acoustic pulses using ultrafast lasers. In transparent media, it is often referred to as time-domain Brillouin scattering (TDBS). It provides the opportunity to monitor the propagation of nanometers-length acoustic pulses and to determine acoustical, optical, and acousto-optical parameters of the materials. We report on the application of TDBS for evaluating the effect of Praseodymium (Pr) substitution on the elasticity of multiferroic (Bi1−xPrx)(Fe0.95Mn0.05)O3 (BPFMO) thin films. The films were deposited on Si and LaAlO3 (LAO) substrates by a sol-gel method. X-ray diffraction and Raman spectra revealed earlier that a phase transition from rhombohedral to tetragonal structure occurs at about 15% Pr substitution and is accompanied by the maxima of remnant magnetization and polarization. Combining TDBS with optical spectral reflectometry, scanning electron microscopy, and topographic measurements by atomic force microscopy, we found that the structural transition is also characterized by the maximum optical dielectric constant and the minimum longitudinal sound velocity. Our results, together with earlier ones, suggest that BiFeO3-based films and ceramics with compositions near phase boundaries might be promising materials for multifunctional applications.
