“…Moreover, the influence of different ns pulsed irradiations in Cu/Ag/AZO multilayer films has been investigated to improve the optical and electrical properties of films [46]. In contrast, saturable absorption has been measured in ZnO films at 1560 nm [47], which can be tailored during the processing route of the synthesis [48]. Moreover, it has been pointed out that an increase in light scattering is necessary to obtain a higher transmittance in AZO films [49].…”

Simultaneous interrogation of pump and probe beams interacting in ZnO nanostructures of a two-wave mixing is proposed for dual-path data processing of optical signals by nonlinear optical effects. An enhancement in third-order nonlinear optical properties was exhibited by Al-doped ZnO thin films. Multiphoton absorption and nonlinear refraction were explored by the z-scan technique at 532 nm with nanosecond pulses. The evolution of the optical Kerr effect in the ZnO thin films was analyzed as a function of the incorporation of Al in the sample by a vectorial two-wave mixing method. Electrical and photoconductive effects were evaluated to further characterize the influence of Al in the ZnO solid samples. Potential applications of nonlinear optical parameters for encoding and encrypting information in light can be envisioned.

“…The temperature rise against laser intensity is shown in Fig. (3). We can see the increasing temperature with laser intensity according to equation (1); when the intensity increases above 10 GW/cm 2 , aluminum melting occurs, where the melting point of aluminum is 660.3 °C [9].…”

“…The ionization process involves removing or adding electrons to the atoms or molecules, creating charged particles. The plasma, consisting of ionized particles, can exhibit a slightly conical or cylindrical shape due to the dynamics of the shock wave and the interaction with the surrounding environment [3][4][5][6][7][8].…”

“…The shock wave can also cause the ejection of small particles or debris from the surface of the aluminum; the characteristics of the laser-induced shock wave, such as its amplitude, duration, and spatial distribution, depend on factors such as the laser energy, pulse duration, spot size, and the optical and mechanical properties of the aluminum. These parameters can be adjusted to control and optimize the desired effects on the aluminum material [3]. Applications of laser-induced shock waves in aluminum processing include material shaping, surface modification, and surface cleaning.…”

Non-destructive laser testing (NDLT) or laser shock penning (LSP) describes the no-damaging material testing method by employing a laser; this denies damaging or inducing helpfulness to give information about a material or component. The experimental study examined the physical characteristics of aluminum and compared it with normalized Hugoniot data. The experimental data depends on studying super eye images supported by SEM images to study the track effect induced by different energy of nanosecond Nd-YAG laser in Laser-Induced Shock Peening (LSP). The forward velocity of the shock wave depends on the material and the sample's shocked medium related to the excised atoms' ionization rates. It noted that the LSP of Al in water and ethanol is the closest to the little shock Hugoniot data pressure is 4.5 GPa, while it is typically (0.46,3.2, and 3) GPa when the incident laser intensity is 11.4 GW/cm2 in air, water, and ethanol media. NDLT technique could apply to examine material shock properties like (particle velocity, shock time, shock wavelength, shock energy, shock intensity, loudness, and force) which is essential to finding mechanical properties. We compared NDLT with classical measurements where Stress-Strain was measured by Tensile test, and the hardness was measured by Vicker hardness; we found the shocked Al in water and ethanol gives more matching for the tensile test. The Vickers hardness more matching when shocked Al in water. In addition, the Elastic Modulus value by the Tensile test is 28 GPa, while by NDLT is (8.4MPa, 4.9, 4.7G Pa) in air, water, and ethanol media.
