GLOPhotonics, Limoges, France is leading the way in the development and commercialisation of fibre-based Beam Delivery Systems (BDS) for ultra-short pulse high-power lasers used in materials processing applications. Developed by GLOphotonics in conjunction with IFSW, University of Stuttgart during the HIPERDIAS H2020 project (see left-hand picture below) it takes advantage of the unmatched performances of Hollow-Core Photonic Crystal Fiber (HC-PCF) for ultra-short pulse beam delivery.
For the first time fiber delivery of 300fs, 150µJ pulses and more than 150W has been reported with close to 90% transmission efficiency and unchanged beam quality (see right-hand pictures above). To achieve such performances GLOphotonics had to develop a fiber sealing method to handle both air non-linearity caused by such high peak power and thermal load induced by multi hundred-watt laser. Jerome Alibert, Chief Executive Officer, is excited by the potential of the technology to help grow the adoption of high-power lasers in micro-machining applications where the delivery of the beam to the work-piece requires the safety and flexibility of fibre delivery: “GLOPhotonics has an opportunity to establish a pre-eminent position in a number of micro-machining applications in the next few years. Ultra-fast lasers with multi hundred-watt average power, are expected to see a significant uptake in the micro-machining market in Europe, Asia and North America and we hope to be amongst the leaders in providing affordable, high performance, safe fibre-based beam delivery systems into this market space”.
