Measurement and analysis of species distribution in laser-induced ablation plasma of an aluminum-magnesium alloy

Junxiao Wang et al.

Summary: We proposed a theoretical spatio-temporal imaging method based on thermal and hydrodynamics models, which can obtain clear species distribution images in plasma through image processing. Simulations of plasma with different laser energies showed consistent results with experimental data, especially at low laser energy.

Numerical simulation of the effect of laser wavelength on nanosecond laser ablation and plasma characteristic

Q. Min et al.

Summary: A two-dimensional axisymmetric radiation hydrodynamics model was developed to study the effect of excitation laser wavelength on aluminum target evolution, plasma generation, and plasma characteristics. The study found significant differences in laser absorption mechanisms and plasma formation between 1064nm and 266nm radiation.

Two-dimensional axisymmetric radiation hydrodynamics model of moderate-intensity nanosecond laser-produced plasmas

Qi Min et al.

Summary: In this study, a two-dimensional axisymmetric radiation hydrodynamics model is proposed to simulate nanosecond laser ablation of a solid target under varying pressures and in different gases. The model is validated by comparing the simulation results with experimental data obtained using multiple diagnostic tools. This model provides a numerical tool for interpreting experimental data in moderate-intensity nanosecond laser ablation when the target surface temperature remains below the critical value.

Investigating laser ablated plume dynamics of carbon and aluminum targets

Mikhail Finko et al.

Summary: Recent high-resolution images of nanosecond laser ablation plumes show a strong correlation between the internal plume structure and the material being ablated, but the details of this relationship are not yet well understood. In this study, a 2D radiation hydrodynamics model is used to investigate the dependence of internal plume structure formation on the ablation material. Experimental measurements are compared with model predictions, including synthetic emission maps. The results show good agreement between the shape and expansion rate of the outer air plume region for carbon and aluminum, as well as the inner material plume dynamics for carbon ablation. However, discrepancies are observed in the case of polished aluminum target.

Numerical simulation of nanosecond laser ablation and plasma characteristics considering a real gas equation of state

Qiang Liu et al.

Summary: A two-dimensional axisymmetric model for ns-laser ablation considering the Knudsen layer and plasma shielding effect has been developed. The evolution of the target surface during laser ablation can be divided into three stages: surface temperature increase, evaporation, and condensation. The internal energy distribution indicates the significance of ionization and excitation energy during laser ablation in the plasma.
