Argus Laser News and Tips for using

This study developed a hybrid manufacturing method integrating nanosecond laser direct drilling and electroless copper plating for high-hardness and high-brittleness aluminum nitride (AlN) ceramics. The effects of three atmospheres—air, water, and argon—on microhole quality were compared. The results show that microholes processed in an argon (Ar) atmosphere exhibit the optimal geometry, with a metallic aluminum content as high as 97.47% on the hole wall, which effectively induces a dense and uniform electroless copper plating layer. Ultimately, high-quality metallized microholes with a resistance as low as 7.35 mΩ were achieved, providing a reliable interconnection solution for high-density electronic packaging and heat dissipation substrates.

The article reviews the latest developments and future prospects of beam shaping technology in laser welding. It discusses how different beam morphologies—such as Gaussian, elliptical, flat-top, and dual-mode beams—control molten pool dynamics to reduce defects like porosity and spatter, especially in high-reflectivity materials like aluminum and copper.

As the global DIY and personal manufacturing markets expand—spanning Maker education, home workshops, and designer startups—more people are looking to experience the thrill of "making anything." Within the "Big Three" of desktop fabrication, 3D printing and CO2 laser engraving have already matured,

In response to the surging demand for laser processing in industries such as window & door, ladder, auto parts, and animal husbandry, and given the massive price gap ($10k to $100k+), this guide is designed to help you see through the fog and make wise investment decisions.1.

This study introduces an in-situ monitoring method for laser processing based on specular reflection of the molten pool surface, enabling high-resolution observation and feature extraction of molten pool dynamics. By analyzing the molten pool surface, keyhole opening, and specular micro-region under varying laser powers, it identifies the specular micro-region as the most sensitive and representative parameter due to its strong periodic behavior linked to laser–keyhole interactions. The findings provide a novel approach for understanding energy transfer mechanisms and offer a reliable foundation for real-time monitoring and intelligent control in laser manufacturing processes.

This study demonstrates that high-speed spiral oscillation laser-arc hybrid welding combined with Er-Zr microalloyed filler effectively improves weld formation and mechanical performance in Al-Mg alloys. By optimizing oscillation parameters and suppressing Mg segregation through laser-induced stirring, the process achieves defect-free welding, refined microstructure, and enhanced strength and ductility, offering a highly efficient and cost-effective solution for medium-thick aluminum alloy welding in shipbuilding applications.
