Optical fibre lasers offer significant benefits in comparison to other laser sources, such as extremely low thermal lensing, extraordinary good beam quality and very high plug efficiency. Optical fibre lasers have worldwide sales in excess of $300M and a predicted annual growth rate of 20-40%, thus are rapidly replacing other types of more conventional lasers. Indeed, the increasing deployment of high power fibre lasers in manufacturing has improved consumption efficiency. Up to date only near-IR sources have been manufactured in fiberized forms. The challenge is to develop new fiberized sources in the mid-UV. The successful manufacture of optical fibre lasers would have numerous applications which include, amongst others, water purification, insulators (such as plastics or glass) marking and processing, explosive detection, forensics and counter measures. This projects aim to demonstrate the possibility to use solid silica fibres to efficiently generate light in the UV. The proposed programme spans from the manufacture of specialty silica fibres transparent to the UV, doped with novel lasing elements, the design of fiberized laser pumps, and their combination in suitable systems to produce a new generation of affordable higher performance lasers. A variety of lasers with wavelength in the range 170nm to 330 nm will be developed and their applications in Raman spectroscopy and supercontinuum generation will be investigated.

与其他激光源相比，光纤激光器具有显着的优势，例如极低的热透镜效应、出色的光束质量和非常高的插头效率。光纤激光器的全球销售额超过 3 亿美元，预计年增长率为 20-40%，因此正在迅速取代其他类型的更传统的激光器。事实上，高功率光纤激光器在制造业中的越来越多的部署提高了消费效率。迄今为止，仅以纤维化形式制造近红外光源。挑战在于开发新的中紫外纤维化光源。光纤激光器的成功制造将有许多应用，其中包括水净化、绝缘体（例如塑料或玻璃）标记和加工、爆炸物检测、取证和对策。该项目旨在展示使用固体二氧化硅纤维有效产生紫外线的可能性。拟议的计划涵盖了对紫外线透明的特种石英光纤的制造、掺杂新型激光元件、光纤化激光泵的设计以及它们在合适的系统中的组合，以生产新一代价格实惠的高性能激光器。将开发波长在170nm至330nm范围内的各种激光器，并研究它们在拉曼光谱和超连续谱产生中的应用。
