“…When polarization selective detection is done, even information about the rotational relaxation can be extracted [7]. Also, in the reflection mode, the signal-to-noise ratios achieved by ISS in the heterodyne detection mode are quite satisfactory [1,2,28,31], even for rough samples [32].…”

In recent decades, the impulsive stimulated scattering (ISS) method, which is based on photothermal and photoacoustic phenomena, has been successfully used to simultaneously investigate the thermal and elastic properties in a four-wave mixing configuration, both in transmission in semitransparent materials and on reflecting surfaces of solids. In this report, an extension of the technique is proposed to study a laser-induced thermoelastic response at the free surface of glass-forming liquids. The employed all-optical configuration allows extraction of information about the acoustic shear modulus in the MHz frequency range, and hence is complementary to the classical ISS configuration in the transmission mode, which is suitable to study the relaxation of the longitudinal acoustic modulus, and to another earlier reported ISS configuration, which is exciting and probing laser-induced thermoelastic phenomena at a liquid-solid interface. A theoretical model is presented and numerically illustrated for the glass transition of glycerol, and experimentally validated for water at room temperature.

“…32 TG spectroscopy with changing analysis depths has been used to reconstruct depth profiles of Rayleigh wave velocity and elastic constants. 35,36 TG spectroscopy was also used to determine the thickness of amorphized layers of ion-implanted silicon, 37 simultaneously acquiring the layer's density, Young's modulus, and Poisson's ratio. Similar changes were investigated in lithium niobate thin films during ion implantation, 17 suggesting that TG spectroscopy is equally viable as an in situ technique, with the added advantage of being a noncontact method.…”

The ability to study radiation damage in situ will directly enable the rapid innovation and qualification of materials for nuclear applications by allowing direct observation of the effects of radiation damage accumulation. This is a challenging task, as the measurement technique must be noncontact, nondestructive, rapid, and still allow for online irradiation without interference. Applicable methods of mechanical spectroscopy are surveyed, noting their potential usefulness for characterizing radiation-induced microstructural changes in situ. The transient grating (TG) spectroscopy technique appears most suited for these studies, due to its noncontact, nondestructive nature, its ability to rapidly probe materials to the depth of ion irradiation, and the large number of deconvolvable components extractable from its signal. Work is proposed to separate the individual mechanisms of irradiation damage using in situ and ex situ TG spectroscopy, through a suite of single-effect and integrated experiments.

“…For thermal grating decay, Käding (42) showed that the measurement is sensitive to thermal properties up to a depth of L/π, while a surface layer of thickness L/2 dominates the measured SAW signal (44). This ability to target different probing depths makes TGS measurements very attractive for selectively probing the properties of thin surface regions, or even depth profiling of properties (45). TGS is particularly useful for studying ion irradiation as it allows probing of the properties of the ion-irradiated layer alone, typically on the same order in thickness as the TGS probe depth, with little contribution from the unirradiated material beneath.…”

Transient grating spectroscopy: An ultrarapid, nondestructive materials evaluation technique

Structure-property relationships are the foundation of materials science.Linking microstructure and material properties is essential for predicting material response to driving forces, managing in-service material degradation, and engineering materials for optimal performance. Elastic, thermal, and acoustic properties provide a convenient gateway to directly or indirectly probe material structure across multiple length scales. We review how using the laser-induced transient grating spectroscopy (TGS) technique, which uses a transient diffraction grating to generate surface acoustic waves (SAWs) and temperature gratings on a material surface, non-destructively reveals the material's elasticity, thermal diffusivity, and energy dissipation on the sub-microsecond timescale, within a tunable sub-surface depth. This technique has already been applied to many challenging problems in materials characterization, from analysis of radiation damage, to colloidal crystals, to phonon-mediated thermal transport in nanostructured systems, to crystal orientation and lattice parameter determination.Examples of these applications, as well as inferring aspects of microstructural evolution, illustrate the wide potential reach of TGS to solve old materials challenges, and to uncover new science. We conclude by looking ahead at the tremendous potential of TGS for materials discovery and optimization when applied in situ to dynamically evolving systems.
