Diode laser technology has the potential to provide significantly more efficient industrial laser sources for materials processing than are currently available. However poor beam quality has so far limited market penetration to a few relatively small niches such as soldering and plastics welding. This project aims to exploit a combination of key technologies held separately by the partner organisations and bring them together to develop fiber coupled diode laser sources with beam qualities good enough to be applicable to broad range of mainstream applications. Specifically this will include a significant increase in the efficiency of current laser based welding processes to the point where they are more efficient than even conventional MIG or other techniques.The main research activities will be 1) Demonstration of prototype energy efficient, high brightness, diode laser (DL) modules at power levels 200-1000W coupled into 0.15mm fibre;2) Development of these modules to prototype standard on a staged basis - allowing parallel work on higher power prototype DL modules; 3) Applications research on DL modules for welding, marking, and cutting. 4) Novel architectures for DL module combination to achieve power/brightness of 4kW into 0.25mm fibre5) Research on energy saving welding processes and applications trials

二极管激光技术有潜力为材料加工提供比目前更有效的工业激光源。然而，到目前为止，较差的光束质量限制了市场渗透到一些相对较小的利基市场，如焊接和塑料焊接。该项目旨在结合合作伙伴组织各自掌握的关键技术，并将它们结合在一起，开发光束质量足够好的光纤耦合二极管激光源，以适用于广泛的主流应用。具体来说，这将包括显著提高当前基于激光的焊接工艺的效率，使其比传统的MIG或其他技术更有效。主要的研究活动将是：1)示范原型节能，高亮度，功率水平为200-1000W的二极管激光（DL）模块耦合到0.15mm光纤；2)分阶段将这些模块开发为原型标准-允许并行开发更高功率的原型DL模块；3)焊接、打标、切割等深度学习模块的应用研究。4)采用新颖的DL模块组合架构，使0.25mm光纤的功率/亮度达到4kW。5)节能焊接工艺研究及应用试验
