Special Issue Information

Dear Colleagues,

With the increasing demand for precision manufacturing, laser cleaning has emerged as a pivotal green photonics technology, effectively replacing traditional chemical and mechanical methods. This Special Issue focuses on the intricate mechanisms of laser–matter interaction during the removal of contaminants such as rust and oxide layers. We aim to explore the critical balance between achieving a high cleaning efficiency and remaining below the substrate damage threshold, particularly in relation to the impact of plasma shockwaves. Furthermore, we seek to address the quantitative characterization of surfaces’ roughness and cleanliness, which are essential for quality control. The topics of interest include novel scanning strategies, real-time monitoring systems, and the optimization of optical parameters to prevent thermal damage while ensuring thorough decontamination. By bringing together cutting-edge research, this Issue will provide a comprehensive overview of the current state and future directions of intelligent laser cleaning technologies.

The efficient removal of tenacious oxide scales from hot-rolled steel surfaces represents a persistent challenge in advanced manufacturing, as traditional manual grinding methods exhibit poor efficiency and environmental compatibility. This investigation develops an innovative methodology, i.e., a “coarse-to-fine” hierarchical cleaning paradigm consisting of dual-stepwise laser cleaning with variable parameters that successfully addresses the restrictive process window inherent to conventional single-parameter techniques. Through a strategically designed sequential treatment protocol—employing initial low-frequency (20 kHz), high-energy-density (200 mm/s) laser irradiation for primary oxide ablation, succeeded by high-frequency (60 kHz), low-energy-density (4000 mm/s) processing for residual scale elimination—we demonstrate an optimal synergy between ablative and thermomechanical vibration mechanisms. Rigorous multi-modal characterization incorporating SEM-EDS microscopy, oxygen content quantification, and metallographic analysis confirms exceptional performance metrics, including 98.7% oxide removal efficiency and 43.2% reduction in substrate surface roughness relative to standard methods. The developed protocol achieves a 2.8-fold expansion of the operational parameter space while establishing a novel “coarse-to-fine” hierarchical cleaning paradigm. These findings offer fundamental insights into laser–matter interactions while delivering a transferable technological framework for high-value manufacturing sectors, particularly in automotive and aerospace component production.
