Advanced ultra-short pulse two-micron fibre lasers for deep tissue medical imaging

该博士项目涉及开发新一代光纤激光器，使其能够在人体深处进行高分辨率、化学敏感的3D激光成像。该项目是EPSRC大型合作赠款的组成部分，旨在满足我们未来的医疗需求。该项目团队包括从事激光开发、先进计算成像方法(包括人工智能)、新信号探测器的工作人员，以及来自爱丁堡大学、诺丁汉大学和南安普顿大学的医学博士。该技术旨在通过使用光(与X射线不同，X光是一种安全的非电离辐射形式)改进疾病的早期检测，最终应提供一种快速、广泛使用的诊断工具，既可提供更好的护理，又可节省未来的成本。例如，英国国家医疗服务体系(http://www.inlightenus.chem.ed.ac.uk/)This)全额资助的PHD项目专注于创造工作在2微米波长区域的新型高性能光纤激光器。这些激光器不仅在医学成像领域，而且在工业处理和光通信领域都有潜力开辟大量新的应用领域。特别是，该项目将创造一种世界领先的飞秒/皮秒脉冲光纤激光光源，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把激光器的输出转换为新成像所需的更长和更短的波长。概括地说，项目学生所做的工作将结合实验和模拟，同时增进我们对激光和非线性光学的理解。

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
