9977677RoccaThis project will develop a table-top soft x-ray laser source of very intense pulses of picosecond duration. The important enabling role of intense soft x-ray coherent radiation in science and technology is well recognized, and has motivated the development of large modem synchrotron radiation facilities. Very recent advances now allow the possibility to develop compact table-top sources of soft x-ray laser radiation with a spatially coherent average power similar to that of a synchrotron beam line, and with more that five orders of magnitude larger peak power. Such table-top sources could greatly impact the national research infrastructure by making intense beams of soft x-ray radiation more widely available, and by enabling new science with the access to a regime of very high soft x-ray peak intensities not presently available.The project will develop a new kind of powerful table-top soft x-ray laser based in the combination of capillary discharges developed in our laboratory with high intensity ultrashort pulse optical laser technology. The combination of these two relatively new but proven technologies should allow the efficient generation of multi-Megawatt picosecond pulses of highly coherent soft x-ray radiation at a variety of soft x-ray wavelengths. The use of a capillary discharge plasma waveguide will allow the PI to make very efficient use of the laser pump radiation, potentially improving the efficiency of laser pumped collisional soft x-ray lasers by one to two orders of magnitude. The major concepts that will enable the proposed research development have been tested experimentally. The proposed development has potential, in collaboration with industry, to make these table-top lasers accessible to a broad community of scientists and engineers nationwide.***

9977677RX100该项目将开发一个桌面软X射线激光源，其脉冲非常强，持续时间为皮秒。 强软x射线相干辐射在科学技术中的重要作用是众所周知的，并推动了大型现代同步辐射设施的发展。 最近的进展现在允许开发紧凑的桌面软X射线激光辐射源，其空间相干平均功率类似于同步加速器光束线的功率，并且峰值功率大五个数量级。 这样的桌面光源可以使软X射线辐射的强光束更广泛地使用，并通过使新的科学能够获得目前无法获得的非常高的软x射线峰值强度。该项目将开发一种新的强大的桌面软x射线，利用本实验室研制的毛细管放电与高强度超短脉冲光激光技术相结合的方法，研制了一种新型的超短脉冲光激光器。 这两种相对较新但经过验证的技术的组合应该允许在各种软X射线波长下有效地产生高度相干的软X射线辐射的多兆瓦皮秒脉冲。 毛细管放电等离子体波导的使用将允许PI非常有效地利用激光泵浦辐射，潜在地将激光泵浦碰撞软X射线激光器的效率提高一到两个数量级。 主要的概念，将使拟议的研究开发已经过实验测试。 拟议的开发有可能与工业界合作，使这些台式激光器能够被全国范围内的科学家和工程师广泛使用。
