“…3.2 Phase Field (PF) Method PF method is a powerful computational approach to solve interfacial problems, such as micro and mesoscale crystal morphology and microstructure evolution [154]. It is widely applied in the research topics such as solidification [106,[114][115][116]155], microstructure evolution [156,157], grain growth [103,112,158], dislocation [159], crack propagation [160] and so on.…”

In this work, we conducted an experimental study supported by theoretical analysis of single laser ablation of copper to investigate the interaction between laser and material at different sample temperatures, in order to predict the ablation morphology and lattice temperature changes. For investigating the effect of sample temperature on femtosecond laser processing, we conducted experiments and simulated the thermal behavior on femtosecond laser irradiation copper using a two-temperature model. The simulated results showed that both electron peak temperature and the relaxation time required reaching equilibrium increased as initial sample temperature raised. When the sample temperature grew from 300 K to 600 K, the maximum lattice temperature at the copper surface rose by about 6500 K under femtosecond laser irradiation, and the ablation depth increased by 20%. The simulated ablation depths followed the same general trend as the experimental values. This work provides some theoretical basis and technical support for the development of femtosecond laser processing in the field of metal materials.

“…Because an ultrashort pulse laser has an ultrashort pulse duration and a very small radiation radius, it is difficult to observe the change in the morphology and the temperature distribution of ultrafast picosecond laser grooving. Due to these limitations, the numerical simulation method can be applied to study the morphology and temperature distribution of ultrafast picosecond laser grooving [3].…”

“…Li and Zhao [7] studied the process of ultrashort-pulse laser radiation on gold film via a dual two-part model and a hyperbolic two-part model. Xue et al [3] combined the phase field model with the 2D two-temperature model to study the effects of laser parameters on the properties of the molten pool and local dendritic morphology. It was found that the maximum temperature gradient has a significant impact on local dendritic competition.…”

The chief aim of this paper is to control groove morphology precisely. In this paper, a 2D temperature field model for ultrafast picosecond laser grooving was set up on the foundation of the two-temperature model coupled with the phase change model. Then, a series of simulations were executed to investigate the influence of laser parameters such as laser power, scanning speed and repetition rate on ultrafast picosecond laser grooving. Finally, a number of experiments were performed to verify the model. The results suggest that the laser power has an obvious influence on the groove width and depth because the heat-affected zone area and single-pulse laser energy increase when the laser power varies from 2 W to 5 W. Obvious impacts of scanning speed on the groove depth and quality are observed in the present simulation due to the variation of overlap between sequential pulses and pulse numbers. The groove width and quality depend on the repetition rate. This is because the increase in the repetition rate has a certain contribution to increasing the temperature of heat residue and pulse number. This research contributes to present theoretical guidance on laser grooving.
