9512282 Rocca This research proposes to develop a unique table-top soft X-ray laser for photochemistry and photophysics studies. This innovative instrument is made feasible by a recent demonstration by the researchers of large soft X-ray amplification in the plasma created by a compact electrical discharge. This breakthrough offers the opportunity for the development of a new type of soft X-ray laser of significantly reduced size and increased simplicity that can operate repetitively. The laser will provide high peak power beams (circa 10 microjoules per nanosecond pulse) of high energy photons (26.5 electron volts) that will permit extension of laser photochemistry and photophysics studies of molecules, clusters, and surfaces to the soft X-ray region. %%% The development of this innovative soft X-ray laser will benefit numerous applications and open new areas of research. These applications include the diagnostics of material surfaces, the testing of optical coatings and soft X-ray optics, diagnostic of dense plasmas and of nuclear detector materials, and high resolution imaging. The compact soft X-ray laser source can also impact basic studies in atomic physics and nonlinear optics. ***

小行星9512282 本研究旨在开发一种独特的台式软X射线激光器，用于光化学和光物理研究。这种创新的仪器是可行的，最近演示的研究人员的大型软X射线放大的等离子体中产生的紧凑的放电。这一突破为开发一种新型的软X射线激光器提供了机会，这种激光器的尺寸大大减小，并且可以重复操作。该激光器将提供高能量光子（26.5电子伏）的高峰功率光束（约10微焦耳/纳秒脉冲），这将允许将分子、团簇和表面的激光光化学和微物理学研究扩展到软X射线区域。 这种创新的软X射线激光器的开发将使许多应用受益，并开辟新的研究领域。 这些应用包括材料表面的诊断、光学涂层和软X射线光学的测试、致密等离子体和核探测器材料的诊断以及高分辨率成像。紧凑型软X射线激光源还可以影响原子物理和非线性光学的基础研究。 ***
