Fabrication of micrometre-sized periodic gratings in free-standing metallic foils for laser-plasma experiments
文献摘要：
Engineered targets are expected to play a key role in future high-power laser experiments calling for joined,extensive knowledge in materials properties,engineering techniques and plasma physics.In this work,we propose a novel patterning procedure of self-supported 10 μm thick Au and Cu foils for obtaining micrometre-sized periodic gratings as targets for high-power laser applications.Accessible techniques were considered,by using cold rolling,electron-beam lithography and the Ar-ion milling process.The developed patterning procedure allows efficient control of the grating and foil surface on large area.Targets consisting of patterned regions of 450 μm×450 μm,with 2 μm periodic gratings,were prepared on 25 mm×25 mm Au and Cu free-standing foils,and preliminary investigations of the micro-targets interacting with an ultrashort,relativistic laser pulse were performed.These test experiments demonstrated that,in certain conditions,the micro-gratings show enhanced laser energy absorption and higher efficiency in accelerating charge particle beams compared with planar thin foils of similar thickness.
