High Efficency Laser Processing Systems (HELPS)

二极管激光技术有可能为材料加工提供比目前可用的更有效的工业激光源。然而，差的光束质量到目前为止限制了市场渗透到一些相对较小的利基，如焊接和塑料焊接。该项目旨在利用合作伙伴组织单独持有的关键技术的组合，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。主要研究内容包括：1）示范功率为200- 1000 W的高能效、高亮度、半导体激光器（DL）模块，并将其耦合到0.15mm光纤中; 2）分阶段将这些模块开发为原型标准-允许在更高功率原型DL模块上并行工作; 3）焊接、标记和切割DL模块的应用研究。4)DL模块组合的新型架构，可在0.25 mm光纤中实现4kW的功率/亮度5）节能焊接工艺研究和应用试验

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 propotype energy effficient, 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
