“…Considering the higher photon energy of visible and UV wavelengths, the PI process should be the main absorption mechanism. However, the IB absorption is dominant at IR wavelength because the IB coefficient is proportional to λ 3 [18][19][20][21]. For laser wavelength of 1064 nm, the incoming laser is easily absorbed by initial plasma through the IB mechanism.…”

“…Among these factors, laser wavelength has a significant effect on lasertarget coupling, ablation rate, penetration depth, plasma ignition threshold, and plasma absorption [17]. Furthermore, photoionization (PI) and inverse bremsstrahlung (IB) are the main mechanisms of energy absorption for different laser wavelengths, which are responsible for the formation and development of plasma [18][19][20][21]. As a result, it is necessary to discuss the influence of laser wavelength on propulsion behaviors.…”

Propulsion performance produced by laser ablation of polymer made of acrylonitrile butadiene styrene (ABS) is experimentally investigated using the first, second, and third harmonics of a Nd: YAG laser. A ballistic pendulum is employed to assess the impulse and coupling coefficient for laser propulsion application. Fast photography, target ablation, and optical emission spectroscopy are proposed to analyze the energy coupling characteristic. The impulse and coupling coefficient under different pressures are demonstrated to depend on the target ablation and plasma properties which are relevant to laser wavelength. As the laser wavelength decreases, the crater depth and ablation mass are enhanced. Meanwhile, the plasma plume separates at atmospheric pressure and its length extends continuously in the low-pressure range. As a result, plasma including more ejected particles with higher velocity contributes to obtaining excellent impulse and coupling coefficient. In addition, the decreased electron density and temperature indicate higher collision frequency and photoionization dominate rather than inverse bremsstrahlung absorption at shorter laser wavelengths. This work provides a better understanding of the energy conversion mechanism and a reference for improving propulsion performance.

“…Aberkane et al 31 investigated the influence of a 50 mJ Nd: YAG laser with wavelengths 1064, 532, and 355 nm at 7, 9, and 10 ns pulse durations, respectively, on the relationship between Te and surface hardness of Fe-V-C metallic alloys. They determined that employing an excitation laser in the IR range rather than in the UV range is more efficient for measuring surface hardness using LIBS.…”

In this work, we present studies on the effect of laser wavelengths on the laser-induced plasma characterization using a femtosecond (fs) ytterbium-doped potassium-gadolinium tungstate (Yb:KGW) laser. Plasma plumes of copper, steel, ceramics, and glass samples were induced using a multiple shot of 200 fs laser pulses with 1030 nm and 343 nm wavelengths at fixed laser fluence ([Formula: see text]) and analyzed using the laser-induced breakdown spectroscopy (LIBS) technique. Time-resolved fs-LIBS measurements were performed on the same set of samples and under the same experimental conditions. For the calculation of plasma parameters, the set of spectral lines of Cu(I) (for copper sample), Fe(I) (for steel sample), and Ca(I), K(I) (for glass and ceramics samples) were observed. The plasma electron temperature and density were evaluated from the Boltzmann plots and Stark-broadening profiles of the plasma spectral lines, assuming the local thermodynamic equilibrium condition. Time-resolved plasma temperature and electron density for fs-LIBS using ultraviolet (UV) and infrared (IR) laser wavelengths were analyzed and no significant dependence on fs laser wavelength was observed for any of the samples. However, for all samples the signal-to-noise ratio (SNR) significantly increased using UV laser radiation: copper ([Formula: see text]), steel ([Formula: see text]), glass ([Formula: see text]), and ceramics ([Formula: see text]). Therefore, by using a fs UV laser wavelength for laser-induced breakdown spectroscopy experiments, for certain materials the SNR and at the same time the limit of detection can be significantly enhanced.

“…Recently, its application as an innovative method for in situ characterizing materials’ surface mechanical properties has been validated frequently. 11–36 All papers found regarding this topic used materials with strengths much larger than dozens of MPa (hereinafter defined as solid materials) such as concretes, 11 mineralized biological materials, 12–15 bulk metals, 16–28 ceramics, 29,30 stones, 31–35 and pharmaceutical tablets. 36 In almost all of these papers, the method was developed in light of the role of the shock wave in the expansion of a laser-induced plasma from a solid material after the end of a laser pulse.…”
