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.

目前仅在数十亿美元的自由电子激光设施中发现的强烈飞秒极紫外（XUV）源正在物理学，化学，量子技术，生物学和医学中开辟新的机会。在这个项目中，我们建议应用T. Ozaki的小组（INRS-EMT）在激光烧蚀介质产生高次谐波方面取得了重大进展，将这种强XUV光源的尺寸和成本降低到更适中的实验室规模（适合标准的大学实验室，总成本<100万美元），从而大大提高了这种光源的可及性。特别是，我们将研究使用强烈和高效的谐振谐波（RH），与效率是一个数量级高于传统的气体谐波。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（> 1 μJ/脉冲）极紫外光源（FAMEUS），或法语中的“la source Femtoseconde d 'Ultraviolet extrême à haute puissance Moyenne et à haute Énergie（FUMMIE）”。我们将与少数周期公司合作。发展一种高能的，波长可调谐的飞秒激光器在可见光和近红外区，我们将研究RH从各种目标。这项研究将提供数据，使我们能够设计具有> 10 mW（FAMEUS+）的更高平均功率的FAMEUS。通过这个项目，少周期公司。此外，该公司还将获得专业知识，并获得FAMEUS商业化许可证的第一个选择，这将吸引科技界的极大兴趣。此外，我们将与Axis Photonique Inc.合作。为FAMEUS开发一个终端站，并使用它来表征他们的新XUV相机。使用FAMEUS终端站，Axis Photonique将能够为潜在客户提供有关其相机的FEL实验的具体数据，使他们及其XUV相机与竞争对手相比具有显著的竞争优势，从而使公司得以发展。
