The research of FTMC laser specialists was featured on the cover of the journal “Advanced Engineering Materials”
FTMC laser specialists’ article selected as the main research of November in “Advanced Engineering Materials” journal, with its illustration on the cover.
The article, titled “Efficient ablation, further GHz burst polishing, and surface texturing by ultrafast laser”, was written by Dr. Mindaugas Gedvilas, senior researcher at the Laser Microprocessing Technologies Laboratory, Department of Laser Technologies of FTMC, Dr. Andrius Žemaitis, the researcher and Dr. Paulius Gečys, the Head of Laboratory.
Wiley-VCH, the German publishing house actively engaged in academic and professional publishing, is part of the US publisher John Wiley & Sons, widely known as WILEY. Founded in 1921, Wiley-VCH primarily focuses on a variety of fields, including science, technology, medicine, and research. It is recognized for publishing numerous peer-reviewed journals, books, encyclopedias, and databases. “Advanced Engineering Materials”, part of the prestigious “Advanced” journal portfolio, focuses on the latest breakthroughs in the field of engineering materials.
Dr. Mindaugas Gedvilas, corresponding author and creator of the cover illustration, explains that the paper demonstrates fast and high-quality 3D cavity milling (precision cutting) in metal using a laser. “To increase the efficiency of high-power lasers, optimization of the laser beam size and the number of light pulses in the burst (a specific series) was applied, which resulted in an ablation rate of 13 mm³/min. Complex-shaped cavities were produced by laser milling metal layer by layer.”
The paper also demonstrates the formation of surface structures on stainless steel due to the impact of laser radiation. A low roughness of the laser-treated surface was achieved by polishing with GHz pulse frequency bursts. It was shown that the shapes of stainless steel used for light-emitting diode (LED) diffusers (which are part of the LED components’ secondary optics) can be made using a modern femtosecond laser source, operating with various temporal pulse schemes, enabling the achievement of the desired surface finish,” – says the scientist, adding that the results of this research will contribute to the successful integration of lasers in companies producing micro-molding forms.
