In this paper, we propose a plasma lens to flexibly resize the laser beam by utilizing the laser self-focusing effect. Using a fixed conventional focusing system to focus the laser a short distance in front of the plasma, we can adjust the effective laser beam waist within a certain range, as if a variety of focusing systems were used with the plasma lens acting as an adjustable eyepiece in a telescope. Such a setup is a powerful tool for laser wakefield accelerator experiments in state-of-art petawatt laser projects and allows for scanning focal spot parameters.}, month = {May}, date = {2019-05-05}, organization = {Laser-Plasma Accelerator Workshop, Split (Croatia), 5 May 2019 - 10 May 2019}, cin = {FLA}, cid = {I:(DE-H253)FLA-20120731}, pnm = {631 - Accelerator R $\&$ D (POF3-631) / PWA - Research group for plasma-based accelerators (PWA-20150304) / Plasma wakefield concepts for the synthesis of high-energy, high-brightness electron beams $(hhh45_20180501)$ / Electron-injection techniques in plasma-wakefield accelerators for driving free-electron lasers $(hhh23_20140501)$ / ZT-0009 - Plasma Accelerators $(2018_ZT-0009)$ / OSIRIS - Organic Semiconductors Interfaced with Biological Environments (714586)}, pid = {G:(DE-HGF)POF3-631 / G:(DE-H253)PWA-20150304 / $G:(DE-Juel1)hhh45_20180501$ / $G:(DE-Juel1)hhh23_20140501$ / $G:(DE-HGF)2018_ZT-0009$ / G:(EU-Grant)714586}, experiment = {EXP:(DE-MLZ)External-20140101}, typ = {PUB:(DE-HGF)6}, eprint = {1901.07974}, howpublished = {arXiv:1901.07974}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:1901.07974;\%\%$}, url = {https://bib-pubdb1.desy.de/record/427825}, }
