Tuneable short-wavelength infrared mode-locked fibre lasers

该项目旨在开发新技术，以产生短波红外（SWIR）光谱区的激光脉冲（锁模）。这是由于需要在这些波长下工作的可靠且可调谐的源，用于各种应用，特别是集中在医疗诊断和手术上，并且包括成像、感测和通信。我们计划通过开发基于Thurons增益介质的超快光纤激光器来克服现有脉冲激光源发射约2微米波长的限制，该超快光纤激光器以自启动方式产生脉冲，具有容易控制的特性（例如重复率和中心频率），该项目将联合收割机结合PI的专业知识，（来自阿斯顿大学阿斯顿光子技术研究所的佩雷戈博士）在光脉冲产生新技术的数值建模和设计方面，与合作伙伴（来自德国耶拿莱布尼茨光子技术研究所的Maria Chernysheva博士）在SWIR光谱区工作的光纤激光器方面的实验专业知识。

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.
