"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)" The objective of this research is to develop an extreme ultraviolet/soft x-ray laser for the table-top generation of high brightness coherent short wavelength light. The high average power and pulse energy produced by this light source will enable new nano-scale science and technology applications of high intensity soft x-ray light in a small laboratory setting. The approach combines recent advances in the amplification of soft x-ray light in dense plasmas with a high energy, high repetition rate, optical laser specifically designed to drive soft x-ray lasers. This bright table-top short wavelength laser will make possible the implementation of powerful microscopes that will visualize phenomena in materials, devices, and biological specimens with nanometer spatial resolution and picosecond temporal resolution; modify and characterize materials at the nanoscale, and investigate extreme states of matter that are beyond the reach of optical probes. Since lasers and imaging of the nano-world are subjects that resonate with the intellectual curiosity and interest amongst a broad group of students, the new light source will offer the opportunity to involve in research students ranging from K-12 to graduate school. In addition to exciting multi-disciplinary, cutting?edge thesis projects for graduate students, the proposed soft x-ray laser beam line will create new opportunities to engage undergraduates, high school students, and middle school teachers in scientific research and systems engineering. Diverse participation in the development and use of the proposed laser source will be facilitated by the collaboration with partner institutions serving populations that are underrepresented in science and engineering.

“该奖项是根据2009年的《美国回收与再投资法》（公法111-5）资助的。”该研究的目的是开发一种极端的紫外线/软X射线激光器，以构成高亮度连贯的短波长光线。该光源产生的高平均功率和脉搏能量将使高强度软X射线光在小实验室环境中实现新的纳米级科学和技术应用。 该方法结合了在密集的等离子体中柔软X射线光的放大，具有高能量，高重复速率，专门设计用于驱动软X射线激光器的光学激光器的最新进展。 这个明亮的桌面短波长激光器将使实现强大的显微镜的实现，这些显微镜将可视化材料，设备和生物标本中的现象，并具有纳米空间分辨率和次秒时间分辨率；修改和表征纳米级的材料，并研究超出光学探针范围的物质的极端状态。由于激光和纳米世界的成像是与广泛的学生之间的好奇心和兴趣产生共鸣的主题，因此新的光源将为参与从K-12到研究生院的研究学生提供机会。除了为研究生提供令人兴奋的多学科，切割“边缘论文”项目外，拟议的软X射线激光束系还将创造新的机会，以吸引本科生，高中生和中学教师参与科学研究和系统工程。 与服务于科学和工程领域不足的人群的合作机构的合作，将促进参与和使用拟议的激光来源的开发和使用。
