Special Issue Information
Dear Colleagues,
Ultrafast laser–matter interactions are being explored in order to introduce new pioneering principles and technologies into the realms of fundamental science and industrial production. The local thermal melting and connection properties of ultrafast laser micro-/nanowelding technologies offer a novel method for the welding of diverse transparent materials, thus providing a wide range of potential applications in aerospace, optomechanical systems, sensors, microfluidic, optics, etc.
In this Special Issue, we seek to present the current state of the art in ultrafast laser micro-/nanowelding technology from principles to applications. We aim to show that tuning transient electron activation processes, high-rate laser energy deposition, and the dynamic evolution of plasma morphology at the nanoscale via temporal/spatial shaping methods is able to facilitate the transition from conventional homogeneous transparent material welding to the more intricate realm of transparent/metal heterogeneous material welding. Moreover, the implementation of novel, real-time, in situ monitoring techniques and the prompt diagnosis of welding defects can further be used to improve the strength and stability of welds at the micron scale.
We welcome a wide range of topics, such as the principles of ultrafast laser micro-/nanowelding, bottleneck problems in the welding process, novel welding methods, advances in welding performance, in situ monitoring and diagnosis, image processing and machine learning, and various other applications, to be discussed and presented in this Special Issue.
We hope to offer a forward-looking perspective on the fundamental challenges within the field of ultrafast laser micro-/nanowelding and identify key areas for future research, underscoring the imperative need for ongoing innovation and exploration.
