    Beihang Develops Custom Fabrication Method for Laser-Induced Graphene Smart Honeycombs

    A team led by Professor Luo Sida at Beihang University has developed a fabrication method for laser-induced graphene smart honeycombs with designable structures, allowing control of cell size, shape and graphene clusters. The process combines graphene paper, polyurethane film lamination and resin impregnation and curing, producing structures of about 150×100×10 mm3 and honeycombs with cell sizes from 2 mm to 5 mm. The team also explored applications of a wing-section model in anti-icing and de-icing, pressure sensing and electromagnetic shielding.

    Why we recommend it: Linking laser processing parameters, honeycomb geometry and resin content to performance control offers a process approach for transferring 2D material processing to customizable 3D structures.

    Progress in Passively Mode-Locked Laser Technology with Ring Cavities at Suzhou Institute of Nano-Tech

    A team at the Suzhou Institute of Nano-Tech, Chinese Academy of Sciences, has developed a theoretical model for PML-SRLs, revealing that operating states are governed by the temporal balance of gain and loss. The model combines time-domain traveling-wave equations with partial differential equations for carrier density, examining the relationship among SOA carrier accumulation rate, SA carrier lifetime and ring-cavity round-trip time. The work, published in Optics Express, also found that an SOA with a narrow gain spectrum and a short resonator configuration can merge output pulses to yield high-energy optical pulses.

    Why we recommend it: Putting gain, absorber and cavity round-trip time into a unified dynamic model offers transferable design insight for understanding mode-locking states and pulse merging in semiconductor ring cavities.

    At the Start of the Year, Focuslight and Three Other International Optics Companies Launch an Acquisition Wave

    Focuslight, Synopsys, AMS Technologies and Oxford Instruments announced or completed acquisitions in early 2024, covering micro- and nano-optics, simulation software, laser systems and scientific cameras. Focuslight completed the acquisition of 100% of the equity in SMO for EUR 75.5405 million, while Synopsys plans to acquire Ansys for $35 billion, a deal still subject to shareholder and regulatory approval. AMS Technologies acquired neoLASE, and Oxford Instruments acquired First Light Imaging.

    Why we recommend it: The four deals respectively add device manufacturing, simulation software, laser system and scientific imaging capabilities, useful for comparing different paths optics companies take to expand through acquisitions.

    How Focuslight Laser Solutions Solve Mini and Micro LED Process Challenges

    Focuslight addresses Mini and Micro LED process challenges through laser mass transfer, mass welding and chip repair, with key factors being spot control, energy uniformity and closed-loop temperature control. The Flux H system for mass welding uses a 4000-10000W, 976nm light source, with spot length and width adjustable in segments from 2 mm to 200 mm and energy uniformity above 97%. The Flux H system for chip repair uses a 30-150W, 976nm light source, with a 365um×105um spot and energy uniformity above 90%.

    Why we recommend it: Mapping mass transfer, welding and repair to spot and thermal management requirements provides a concrete method for working backward from display manufacturing bottlenecks to laser system design parameters.
