This project aims to decipher the transient spatio-temporal dynamics of lasers with an emphasis on investigating chaotic instabilities whose fundamental laws are unknown and whose effects impair laser performance in applications with a billion-dollar aggregate value. This project seeks to solve the problem by unravelling the evolving beam's structure on picosecond timescales using an optical device that dissects the beam in space and time. The expected outcome is a suite of tools capable of guiding global efforts to develop next-generation lasers. The discoveries would propel Australia to become a characterisation nexus of the laser industry and usher in the era of faster telecommunication, enhanced sensors and high-precision manufacturing.

该项目旨在破译激光的瞬变时空动力学，重点研究混沌不稳定性，其基本规律未知，其影响在具有数十亿美元总计价值的应用中损害激光性能。这个项目试图解决这个问题，通过使用光学设备在空间和时间上解剖光束，在皮秒的时间尺度上解开不断演变的光束的结构。预期的结果是一套能够指导全球努力开发下一代激光的工具。这些发现将推动澳大利亚成为激光行业的特色纽带，并开启更快的电信、增强的传感器和高精度制造的时代。
