This PhD project concerns the development of a new generation of fibre lasers tailored to enable high-resolution, chemically-sensitive, 3D laser imaging deep within the human body. The project is an integral part of a large collaborative EPSRC grant looking to fulfil our future healthcare needs. The project team comprises those working on laser development, advanced computation imaging approaches (including AI), new signal detectors as well as medical doctors from the Universities of Edinburgh, Nottingham and Southampton. Aiming to improve early detection of disease by using light (unlike X-rays a safe non-ionising form of radiation) the technology should ultimately provide a fast widely used diagnostic tool offering both improved care and future cost savings for example the NHS (http://www.inlightenus.chem.ed.ac.uk/)This fully funded PhD project focusses on creating novel, high-performance fibre lasers operating in the two-micron wavelength region. These lasers have the potential to open-up a wealth of new applications not only in medical imaging, but also for industrial processing and optical communications.In particular, the project will create a world leading femto/pico-second pulsed fibre laser source, overcoming the technical challenges currently limiting progress in the field. Nonlinear frequency conversion of the output will transfer the output from the laser to both longer and shorter wavelengths as needed for the novel imaging. In broad terms, the work undertaken by the project student will combine experiments and simulations, together with advancing our understanding of lasers and nonlinear optics

该博士项目涉及开发新一代光纤激光器，旨在实现人体深处的高分辨率、化学敏感的 3D 激光成像。该项目是 EPSRC 大型合作赠款的一个组成部分，旨在满足我们未来的医疗保健需求。该项目团队由从事激光开发、先进计算成像方法（包括人工智能）、新信号探测器的人员以及来自爱丁堡大学、诺丁汉大学和南安普顿大学的医生组成。旨在通过使用光（与 X 射线不同，一种安全的非电离形式的辐射）来改善疾病的早期检测，该技术最终应提供一种快速广泛使用的诊断工具，既可以改善护理，又可以节省未来的成本，例如 NHS（http://www.inlightenus.chem.ed.ac.uk/）这个全额资助的博士项目专注于创建在 两微米波长区域。这些激光器有潜力不仅在医学成像领域，而且在工业加工和光通信领域开辟大量新应用。特别是，该项目将创建世界领先的飞秒/皮秒脉冲光纤激光源，克服目前限制该领域进展的技术挑战。输出的非线性频率转换将根据新颖成像的需要将激光器的输出传输到更长和更短的波长。从广义上讲，该项目学生所做的工作将结合实验和模拟，并加深我们对激光和非线性光学的理解
