提案编号：ECS-0645220提案标题：Career：用于高效生产极端紫外线辐射的飞秒增强腔PI名称：Jones，R.JasonPI研究所：亚利桑那大学该计划的目标是促进亚利桑那大学的超快光学科学教育，同时开发一种高效产生超短极端紫外线光源的新方法。这种方法是利用高精确度的无源光学腔将来自飞秒频率梳的脉冲相干地相加在一起，并在腔内存储单个大大放大的脉冲。这种方法将提供高次谐波产生所需的高激光强度，而不需要大型放大器，同时保持原始激光器的原始高重复频率和相干特性。在极紫外区高效地产生飞秒频率梳的能力将在许多领域产生重大影响。许多原子和分子跃迁对我们对自然的基本理解非常感兴趣，位于光谱的这一部分，用目前的激光光源很难或不可能测量到。此外，改进的下一代原子钟可以从这些窄的、高能的共振中实现。一种高效的极端紫外线光源可能会在不同的领域开辟更多的应用领域，比如表面物理、生物成像和光刻等。该计划将通过本科生和研究生对研究的关键参与，促进亚利桑那大学超快科学的发展。到该计划结束时，预计将开发一门关于超快光学现象的新课程。此外，教育和研究机会将通过与本科生机构的合作而得到加强。

Proposal Number: ECS-0645220Proposal Title: CAREER: Femtosecond Enhancement Cavities for Efficient Production of Extreme-Ultraviolet RadiationPI Name: Jones, R. JasonPI Institution: University of ArizonaThe objective of this program is to promote education in ultrafast optical science at the University of Arizona while developing a novel approach for efficient generation of ultra-short extreme-ultraviolet light sources. The approach is to utilize high finesse, passive optical cavities to coherently add together pulses from a femtosecond frequency comb and store a single, greatly amplified pulse inside the cavity. This approach will provide the high laser intensities required for high-harmonic generation, without the need for large amplifiers, while maintaining the original high repetition frequency and coherence properties of the original laser.Intellectual Merit. The ability to efficiently generate femtosecond frequency combs in the extreme-ultraviolet spectral region will have a large impact in many fields. Many atomic and molecular transitions of great interest to our fundamental understanding of nature lay in this portion of the spectrum and are difficult or impossible to measure with current laser sources. Furthermore, improved next generation atomic clocks can be realized from these narrow, high energy resonances. An efficient extreme-ultraviolet source will potentially open up even more applications across diverse fields such as surface physics, biological imaging, and photo-lithography to name a few.Broader Impact. This program will foster the growth of ultrafast science within the University of Arizona through the critical involvement of undergraduate and graduate students in research. By the end of the program it is expected that a new course in ultrafast optical phenomena will be developed. Furthermore, educational and research opportunities will both be strengthened through collaborations with undergraduate institutions.
