Special Issue Information

Dear Colleagues,

This Special Issue, entitled "Advances in Laser Processing Technology of Materials—Second Edition", invites potential authors to contribute articles and reviews that encompass the broad spectrum of laser–material interactions and the applications of laser technologies. Contributions addressing the laser processing of dielectrics, ceramics, and biomaterials are particularly welcome.

Our goal is to provide a comprehensive platform for sharing cutting-edge research and insights into both fundamental laser–material interaction processes and the wide-ranging applications of laser technology.

Authors are encouraged to submit research articles that advance our understanding of the underlying physics, chemistry, and mechanics of laser–material interactions, either through new models or extensive simulations. These articles may explore topics from the most conventional applications such as laser ablation, welding, and surface modification to the most recent ones, such as additive manufacturing, the synthesis of nanomaterials, micro- and nano-manufacturing, and more.

Additionally, we welcome reviews that synthesize existing knowledge in laser processing technology, offering significant perspectives on the current state of the field and potential future directions.

By fostering collaborations and the exchange of knowledge, this Special Issue aims to contribute to the ongoing progress of laser processing technology, benefitting researchers, engineers, and industries working with materials across the spectrum. Join us in sharing your expertise and discoveries in this exciting field.

The purpose of this work is to demonstrate that laser-induced conductive tracts in AlN ceramic can be applied for fabrication of an integrated resistive heating element. Nanosecond laser processing at a wavelength of 1064 nm of ceramic in vacuum is used for a formation of conductive areas. It is demonstrated that the applied laser fluence and the number of pulses influence strongly the electrical properties of the material in the irradiated zone. The resistance value of the produced tracks with a length of about 4 mm and width of about 1 mm may vary from 17 to about 2000 Ohms, depending on the processing conditions. The material in the processed zone is characterized by means of surface composition, morphology, and electric properties. It is found that the electrical conductivity of the formed structure is based on the ceramic decomposition and formation of aluminum layer. The analysis of the influence of the temperature on the electrical resistance value shows that the material’s conductivity could be preserved after annealing, as in the present study it is confirmed up to 300 °C. The ability of the formed tracks to serve as a basis element of ceramic integrated resistive heater is studied by applying DC voltage. It is found that the fabricated element can be used with a high reliability to about 90 °C without special requirements for contact design and encapsulation. Operation at higher temperatures is also demonstrated as the maximal one achieved is about 150 °C at 10V. The performance of the heater is investigated and discussed as the operation range is defined. The proposed element can be a basis for a design of an integrated heater in ceramic with high stability and applications in everyday life and research. Full article
