“…Fabbro et al [310] proposed a 1D analytical model considering the plasma pressure generated by a glass transparent overlay. Zhang et al [315] improved upon this model later. However, the major shortcomings of this model were that it had multiple free variables that had to come from experimental measurements.…”

Recent years have witnessed a rapid growth of the laser market. Figure 1 shows the recent revenues of laser sales with about 50% increase in revenue over recent four years , which far exceeds the growth of other industrial sectors. More than one third of this revenue belongs to the category of laser materials processing arena. Undoubtedly, lasers have been playing increasingly important roles in various industrial manufacturing sectors. This article is to capture some of important developments in the rapidly growing areas of laser-based manufacturing and materials processing and also describe important technological issues pertaining to various laser-based manufacturing processes. The topics to be covered in this paper include more popularly used processes in industry such as laser additive manufacturing, laser-assisted machining, laser micromachining, laser forming, laser surface texturing, laser welding, and laser shock peening, although there are several additional areas of laser applications. In each section, a brief overview of the process is provided, followed by critical issues in implementing the process, such as properties, predictive modeling, and process monitoring, and finally some remarks on future issues that can guide researchers and practitioners.

“…Parameters relevant to laser ablation, such as the temperature, stress and volume in the laser ablation process are studied in detail. [27,29] is added to the atoms in this region. For shrink boundary condition, the position of the face is set so as to encompass the atoms in that dimension (shrink-wrapping), no matter how far they move.…”

The mechanisms of phase change of argon during picosecond laser internal ablation are studied using molecular dynamics simulations. It is found that propagation of stress wave and fluctuation of temperature are periodical. The phase change process from solid to liquid to supercritical fluid then back to solid occurs as combined results of heating and the propagation of tensile stress wave induced by the laser pulse and the limited internal space.

“…Since argon has simple face-centered cubic (fcc) crystal structure and the interaction between atoms can be precisely and conveniently described by the Lennard-Jones potential, it has been selected as the object to investigate laser ablation and shock wave in a lot of literatures [16,22,24]. In this work, for simplicity, we also choose argon as the crystal material to study and adopt a model similar to Gacek and Wang's paper [22], as shown in Fig.…”

“…In one outstanding work by Zhigilei et al [15], the influence of laser irradiation parameters like laser fluence, pulse duration, and initial temperature of the sample on laser ablation is studied systematically and dynamics of plumes are described in detail. Zhang and Wang explored the long-time material behavior in nanosecond laser-material interaction by using large-scale hybrid atomistic macroscale simulation [16]. Other simulation work about the ablation plume and ejected clusters, evaporation and condensation can be found in literatures [13,[17][18].…”
