The industry’s most innovative people 2024 Anne Henrottin


Organisation: LASEA Role: Project Manager, Innovation Based in: Liège, Belgium Education: Master's in Physical Engineering, specialisations in microfluidics and Electronics Physics, University of Liège


Anne Henrottin, a dedicated Project Manager specialising in innovation at LASEA, is immersed in the development of laser machines that incorporate powerful femtosecond lasers, with outputs reaching up to 1kW. These laser systems are integrated with state-of-the-art multibeam technologies and monitoring systems. The primary goal of this endeavour is to enhance laser processes, achieving unparalleled productivity while maintaining the precision and quality associated with femtosecond laser processing. In addition to this, Henrottin is actively


involved in the realm of microfluidics applications. She says LASEA is pioneering a unique laser machine capable of structuring microchannels and welding chips without physical contact. “The quality and the hermeticity of the


microfluidic chips are improved, making it a good solution for quick prototyping,” she says. Further setting this innovation apart is its ability to integrate biological substances within the microchannels without causing damage during the welding process, which Henrottin believes is a monumental advantage in various scientific and industrial applications. Another facet of Henrottin's work


involves the development of laser solutions that seamlessly integrate Roll-to-Roll systems and employ multiple heads. These advancements are particularly valuable for large-scale treatments in fields such as imprint electronics, aerospace, and photovoltaic technologies. Her efforts are geared towards enhancing efficiency and productivity in these sectors, marking a pivotal step in the evolution of laser technology. “Recently, we achieved a breakthrough


by creating complete microfluidic chips using a single femtosecond laser source and a single machine,” Henrottin says, “enabling contactless, automated processes with high flexibility and quality. Our patented system for welding microchips maintains the integrity of biological substances inside microchannels.” She adds: “The laser solution welds


the two parts without creating a thermal effect in the microchannel. This means biological substances can be integrated inside the microchannel and not destroyed during the welding process, which is a huge advantage.” Henrottin's foremost research priority


she says. This development underscores the versatility and adaptability of laser technology, making it a pivotal player in cutting-edge research and industrial applications. Henrottin believes the photonics industry faces several challenges and threats in the next 12 months. One of the paramount challenges is the need to develop environmentally friendly machines while simultaneously increasing productivity and returns on investment. Solutions are being explored, including the integration of AI to reduce faulty parts, closed-loop systems for reprocessing workpieces, and the development of multipurpose machines. These innovations are poised to reshape the landscape of laser technology, opening up new avenues for progress. Looking ahead, Henrottin sees the


"Recently, we achieved a breakthrough by creating complete microfluidic chips using a single femtosecond laser source and a single machine"


in the coming year is the development of a groundbreaking ultrashort pulsed laser micromachining machine. This innovative system aims to replace traditional manufacturing processes by offering a versatile platform capable of addressing various application-specific challenges. This next-generation laser machine will leverage artificial intelligence to enhance closed-loop corrective systems and boost productivity through multibeam approaches and synchronised laser pulses with precise trajectories. Reflecting on the past 12 months, she identified the selective laser-induced etching technique developed by Fraunhofer ILT as a stand-out photonics technology. This technology enables the high-precision processing of transparent materials, opening up new possibilities for applications in quantum computing and microelectronics,


greatest opportunity for growth in the photonics sector within ecological applications. As sustainability and environmental concerns take centre stage, laser technology offers solutions to improve conventional techniques, reduce environmental impact, and enhance the efficiency of workpieces. Innovations in this domain are expected to experience rapid growth in the next 12 months, aligning with the continuous advancement of laser technology. In Belgium and Europe as a whole, the


focus on producing European technology is a key consideration. This approach aims to offer competitive, cutting-edge, and environmentally-friendly technologies. The region presents both challenges and opportunities for laser technology to position itself as a leader and pioneer solutions to address pressing societal and industrial needs. Henrottin says her proudest moment in photonics thus far is the successful management of the development, proof of concept, and installation of a machine with 64 laser beams. This achievement was part of the European collaborative project MULTIFLEX and involved the integration of a 1kW laser source, a complex optical module, and a control system to manage the 64 beams efficiently.
