项目摘要

Over the last decade, solid-state lasers have been the subject of great interest with a wide range of applications thanks mostly to their superior output-power-to-wall-plug efficiency. However, the limited availability of colours (wavelengths) produced by these lasers forces the user to compromise by utilising a wavelength that is not ideal for the targeted application. Laser systems based on a nonlinear process, called Stimulated Raman Scattering, offer a simple solution to this need. However, the performance and usability of these so-called Raman lasers have traditionally been limited by thermal distortions inherent to the nonlinear process.This project will, for the first time, investigate the implementation of the adaptive control techniques - typically used in astronomy- inside Raman lasers to significantly alleviate this thermal issue. In this way, the behaviour and performance of the laser can be remotely controlled and optimised resulting in superior performance in terms of output power, beam quality and usability. This offers the prospect of several genuine breakthroughs including a range of world-firsts and world-records as well as the transfer of these laboratory-based systems into an engineering context.These significantly enhanced systems will address a wide range of applications including astronomy, environmental monitoring, cosmetics and medicine. For instance, the treatment of a variety of skin diseases such as psoriasis or port wine stain removal will strongly benefit from this project.Finally, knowledge transfer is an important feature of this project with a full strand of activity dedicated to it. The transfer of this technology will be performed within two high profile research groups at Macquarie University, Australia and at the University of Strathclyde. An industrial collaboration with M Squared Lasers will also take place, particularly targeting commercialisation of the final demonstrator.

在过去的十年里，固态激光器一直是人们非常感兴趣的主题，其广泛的应用主要归功于其上级输出功率到墙上插头的效率。然而，这些激光器产生的颜色（波长）的有限可用性迫使用户通过利用对于目标应用不理想的波长来折衷。基于非线性过程（称为受激拉曼散射）的激光系统为这一需求提供了简单的解决方案。然而，这些所谓的拉曼激光器的性能和可用性传统上受到非线性过程固有的热失真的限制。本项目将首次研究在拉曼激光器内部实施自适应控制技术（通常用于天文学），以显著缓解这种热问题。通过这种方式，可以远程控制和优化激光器的行为和性能，从而在输出功率、光束质量和可用性方面产生上级性能。这为几项真正的突破提供了前景，包括一系列世界第一和世界纪录，以及将这些基于实验室的系统转移到工程环境中。这些显着增强的系统将解决广泛的应用，包括天文学，环境监测，化妆品和医学。例如，治疗各种皮肤病，如牛皮癣或去除葡萄酒色斑，将从该项目中受益匪浅。最后，知识转移是该项目的一个重要特征，该项目有一个完整的活动链。该技术的转移将在澳大利亚麦考瑞大学和斯特拉斯克莱德大学的两个知名研究小组内进行。与M Squared Lasers的工业合作也将进行，特别是针对最终演示器的商业化。
