This projects aims at developing novel techniques to generate laser light pulses (mode-locking) in the short-wave infrared (SWIR) spectral region. This is motivated by the need of reliable and tuneable sources operating at these wavelengths for various applications especially focussing on medical diagnostics and surgery, and including imaging, sensing and communications. We plan to overcome limitation of existing pulsed laser sources emitting around 2 micron wavelength by developing ultrafast fibre lasers based on Thulium gain medium which produce pulses in a self-starting way, with easily controllable properties (such as repetition rate and central frequency), and using a robust architecture suitable for out-of-the-lab applications.This project will combine the expertise of the PI (Dr. Perego from Aston Institute of Photonic Technologies, Aston University) in numerical modelling and design of novel techniques for light pulses generation, with the experimental expertise of the Partner (Dr. Maria Chernysheva from Leibniz Institute of Photonic Technologies, Jena, Germany) in fibre lasers operating in the SWIR spectral region.

该项目旨在开发新技术，在短波红外 (SWIR) 光谱区域产生激光脉冲（锁模）。这是因为需要在这些波长下工作的可靠且可调谐的光源来满足各种应用，特别是医疗诊断和手术，包括成像、传感和通信。我们计划通过开发基于铥增益介质的超快光纤激光器来克服现有脉冲激光源发射2微米左右波长的限制，该激光器以自启动方式产生脉冲，具有易于控制的特性（例如重复率和中心频率），并且使用适合实验室外应用的稳健架构。该项目将结合 PI（阿斯顿大学阿斯顿光子技术研究所的 Perego 博士）在数值建模和新型光技术设计方面的专业知识脉冲生成，利用合作伙伴（德国耶拿莱布尼茨光子技术研究所的 Maria Chernysheva 博士）在短波红外光谱区光纤激光器方面的实验专业知识。
