A single trapped Yb\n                    <jats:sup>+<\/jats:sup>\n                    ion is laser-cooled close to the Lamb\u2013Dicke regime to characterize the metalens performance, achieving a full-width at half-maximum (FWHM) of 1.16 \u00b1 0.09\u2009\u03bcm, which aligns closely with the Abbe diffraction limit of 1.15\u2009\u03bcm and outperforms conventional external-cavity lenses (2.37 \u00b1 0.12\u2009\u03bcm) with the same numerical aperture. We further demonstrate near-diffraction-limited imaging of multi-ion systems over the accessible off-axis range. Our results establish the metalens as a superior optical element for ion fluorescence imaging, providing higher resolution for applications in ion position calibration, multi-qubit readout, and precision measurement. Furthermore, this miniaturized and integrable approach overcomes traditional optical constraints, delivering near-diffraction-limited imaging and advancing the development of compact ion trap platforms.\n                  <\/jats:p>","DOI":"10.1364\/ol.607181","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T13:00:07Z","timestamp":1789390807000},"page":"5605","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["High-resolution trapped-ion fluorescence imaging via an integrated metalens"],"prefix":"10.1364","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2247-6133","authenticated-orcid":true,"given":"Pengcheng","family":"Zheng","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0064kty71","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zerui","family":"Huang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0064kty71","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junxia","family":"Li","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0064kty71","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruxin","family":"Zhou","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0064kty71","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peiliang","family":"Liu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0064kty71","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9883-5900","authenticated-orcid":true,"given":"Chaohong","family":"Lee","sequence":"additional","affiliation":[{"name":"Shenzhen University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,10,1]]},"reference":[{"key":"ol-51-19-5605-R1","doi-asserted-by":"publisher","first-page":"5663","DOI":"10.1038\/s41467-024-49241-w","type":"journal-article","volume":"15","author":"Leibrandt","year":"2024","journal-title":"Nat.
