Proposal Number: ECS-9713254 Principal Investigator: Henry Kapteyn Title: Ultrafast laser produced microstructured plasmas for soft X-ray lasers In this resrach, investigations into the generation of soft x-ray radiation form a laser solid interaction will be investigated. An ultrafast laser pulse of intensity of 1016-1018 watts/cm2 is focused onto a solid, creating a highly nonequilibrium plasma. The rapidly heated, rapidly cooled plasma formed from the laser-plasma interaction with the solid emits sub-picosecond x-rays. The material itself can be patterned or "microstructured" for the efficient absorption of the incident laser light and the emission of the x-ray radiation. The heating and cooling of the solid plasma can be tailored by the properties of the material(s) involved and by the microstructure e.g., high destiny grooves etc.. Key to the success of this work is the high intensity, short pulse laser for the initial heating. Compact soft x-ray lasers will have many applications in biology and materials science.

建议编号：ECS-9713254首席研究员：Henry Kapteyn标题：超快激光产生用于软X射线激光的微结构等离子体在本研究中，将研究从激光固体相互作用中产生软X射线辐射的问题。强度为1016-1018瓦/厘米的超快激光脉冲聚焦到固体上，产生高度非平衡的等离子体。激光-等离子体与固体相互作用形成的快速加热、快速冷却的等离子体发出亚皮秒的X射线。为了有效吸收入射激光和发射X射线辐射，可以对材料本身进行图案化或“微结构”。固体等离子体的加热和冷却可以根据所涉及的材料的性质(S)和微结构(如高命运槽等)进行定制。这项工作成功的关键是高强度、短脉冲激光的初始加热。紧凑型软X射线激光器将在生物和材料科学中有许多应用。
