This project aims to understand and to control light-induced processes in atoms by using finely shaped and tailored laser pulses, focusing on efficient production of excited metastable atoms. This is critical for efficient Atom Trap Trace Analysis, the most advanced technique for dating ground water and geological samples. Expected outcomes of this project include new and enhanced knowledge of physics of light-matter interactions, developing an efficient, clean source of excited metastable atoms, and integrating that source into the Australian National Facility for dating geological samples. This should provide significant benefits, such as significant improvement of operational efficiency and productivity of that facility.

该项目旨在通过使用精细形状和定制的激光脉冲来理解和控制原子中的光诱导过程，重点是有效生产受激亚稳态原子。这对于高效的原子陷阱痕量分析至关重要，原子陷阱痕量分析是测定地下水和地质样本年代的最先进技术。该项目的预期成果包括光与物质相互作用物理学的新知识和增强知识，开发高效、清洁的激发亚稳态原子源，并将该源集成到澳大利亚国家地质样本测年设施中。这应该会带来显着的好处，例如显着提高该设施的运营效率和生产力。
