项目简介
High power fibre lasers (HPFLs), developed first at the PG电子官网, have advanced beyond recognition. 在过去20年里，输出功率增长了4个数量级以上, reaching 10kW in a single beam. They are widely used in the most advanced production lines for cutting, 焊接, 3D printing and marking a myriad of materials from glass to steel. 然而，PG电子竞技平台现在已经接近单个光纤激光器所能产生的最大功率. To continue increasing the power, new solutions must be found.
就像现代计算机包含大量的处理器核心而不是单一的高速核心一样, the future for HPFLs is in the combination of multiple fibre lasers. 大量光纤激光器的成功结合将改变制造业. 这样的突破可以控制所有的光特性(如波长), 极化, 强度, 和相位)来创建动态可重构的结构光，根据特定的应用“动态地”改变.
这样的“数字光纤激光器”不仅会使英国成为一个更加繁荣的国家, but also allow us to protect against malevolent drones, build the next generation of efficient, compact particle accelerators, 清理空间碎片, 处理核废料, and all-in-all make the world a better, 更清洁的, 更环保的, 更安全的地方.
PG电子官网最近获得了600万英镑的资助，用于解决与创建“数字光纤激光器”相关的挑战。, and you will be part of this team effort.
你将在一系列新的波长范围内领导高通量荧光显微镜的发展. The 2µm wavelength band (~1850 nm to ~2100 nm), the green wavelength band (~540 nm), and wavelengths in the UV band, offer the potential for huge benefits to industrial laser processing, due to enhanced absorption in a wider range of materials. 当加工和切割一系列材料(如聚合物)时，这些波长提供了大大提高精度和效率的前景, 复合材料, and even biological tissue (e.g. 用于医疗程序). 然而, 在这些波长范围内缩放平均功率，同时保持高质量的光束轮廓是一个重大挑战.
You will be combining theoretical modelling with experimental work, to demonstrate a wide range of critically important breakthroughs, including multi-kW Tm fibre lasers with narrow-linewidths, 以及用于复合材料加工的高功率绿色波长和紫外激光器，用于可再生技术的应用.
