Field sampling in the terahertz domain has had a tremendous impact on the ability to trace such collective excitations. Here, we extend such capabilities and introduce direct sampling of LSPs in a more relevant petahertz domain. The method allows to measure the LSP field in arbitrary nanostructures with subcycle precision. We demonstrate the technique for colloidal nanoparticles and compare the results to finite-difference time-domain calculations, which show that the build-up and dephasing of the plasmonic excitation can be resolved. Furthermore, we observe a reshaping of the spectral phase of the few-cycle pulse, and we demonstrate ad-hoc pulse shaping by tailoring the plasmonic sample. The methodology can be extended to single nanosystems and applied in exploring subcycle, attosecond phenomena.}, cin = {FS-ATTO}, ddc = {660}, cid = {I:(DE-H253)FS-ATTO-20170403}, pnm = {631 - Matter – Dynamics, Mechanisms and Control (POF4-631) / DFG project 390715994 - EXC 2056: CUI: Advanced Imaging of Matter (390715994) / DFG project 194651731 - EXC 1074: Hamburger Zentrum für ultraschnelle Beobachtung (CUI): Struktur, Dynamik und Kontrolle von Materie auf atomarer Skala (194651731)}, pid = {G:(DE-HGF)POF4-631 / G:(GEPRIS)390715994 / G:(GEPRIS)194651731}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:38530705}, UT = {WOS:001191218800001}, doi = {10.1021/acs.nanolett.4c00658}, url = {https://bib-pubdb1.desy.de/record/605270}, }
