Femtosecond high Average-power Micro-joule Extreme-Ultraviolet Source (FAMEUS)

目前仅在价值数十亿美元的自由电子激光设备上发现的强烈飞秒极紫外线（XUV）光源，正在物理学、化学、量子技术、生物学和医学领域开辟新的机会。在这个项目中，我们建议将T. Ozaki小组（INRS-EMT）的研究结果应用于激光烧蚀介质的高次谐波产生，将这种强烈的XUV源的尺寸和成本降低到更适度的实验室规模（适合标准的大学实验室，总成本< 100万美元），从而显著提高这种源的可及性。特别是，我们将研究使用强而高效的谐振谐波（RH），其效率比传统的气体谐波高一个数量级。这些研究的结果将用于开发一种独特而紧凑的飞秒高平均功率（mw级）微焦耳（>.1µJ/脉冲）极紫外源（FAMEUS），或法语“la Source Femtoseconde d'Ultraviolet extrême <s:2> haute puissance Moyenne et <s:2> haute Énergie （FUMÉ）”。我们将与few-cycle公司合作，在可见光和近红外波段开发一种能量充沛、波长可调的飞秒激光器，利用它我们将研究来自不同目标的相对湿度。这项研究将提供数据，使我们能够设计出平均功率更高的FAMEUS （FAMEUS+）。通过这个项目，few-cycle公司也将获得专门知识，并获得FAMEUS商业化许可的第一选择，这应该会引起科学界和技术界的极大兴趣。此外，我们将与Axis Photonique Inc.合作开发FAMEUS终端站，并使用它来表征他们的新XUV相机。使用FAMEUS终端，Axis Photonique将能够向潜在客户提供与FELs相关的相机实验的具体数据，使他们和他们的XUV相机与竞争对手相比具有显着的竞争优势，从而使公司得以发展。

Intense, femtosecond extreme ultraviolet (XUV) sources, currently found only at billion-dollar free-electron laser facilities, are opening new opportunities in physics, chemistry, quantum technology, biology and medicine. In this project, we propose to apply the findings by T. Ozaki's group (INRS-EMT) in high-order harmonic generation from laser ablation media, to reduce the size and cost of such intense XUV sources to a more modest laboratory scale (fitting in a standard university laboratory, with < $1 million total cost), thereby significantly increasing the accessibility of such sources. In particular, we will study the use of intense and highly efficient resonant harmonics (RH), with efficiencies that are an order of magnitude higher than conventional gas harmonics. The results of such studies will be used to develop a unique and compact Femtosecond high Average-power (mW-class) Micro-joule (> 1 µJ/pulse) Extreme-Ultraviolet Source (FAMEUS), or « la source Femtoseconde d'Ultraviolet extrême à haute puissance Moyenne et à haute Énergie (FUMÉ) » in French. We will work with few-cycle Inc. to develop an energetic, wavelength-tunable femtosecond laser in the visible and near-infrared regime, with which we will study RH from various targets. This study will provide data that will allow us to design FAMEUS with an even higher average power of > 10 mW (FAMEUS+). Through this project, few-cycle Inc. will also gain the expertise and be given the first option of license to commercialize FAMEUS, which should attract significant interest from the scientific and technological community. Further, we will work with Axis Photonique Inc. to develop an endstation for FAMEUS and use it to characterize their new XUV camera. Using the FAMEUS endstation, Axis Photonique will be able to provide to potential customers concrete data on their camera on experiments relative to FELs, giving them and their XUV camera a significant competitive advantage compared with their competitors, thus allowing the company to grow.
