To the best of our knowledge, this fiber, comprising five sets of nested double-layer capillaries around the air core, is the first nested AR-HCF fabricated using infrared glass. Benefiting from the enhanced light confinement capability of the nested capillary design, the fabricated fiber achieves a low transmission loss of 0.15\u2009\u00b1\u20090.04\u2009dB\/m at a single wavelength of 4.65\u2009\u03bcm measured by cutting from 3\u2009m to 1\u2009m. A 0.8-m-long nested tellurite AR-HCF delivers near-diffraction-limited laser output, with a beam quality (M\n                    <jats:sup>2<\/jats:sup>\n                    ) of 1.07. Numerical simulations confirm that the nested structure reduces confinement loss by approximately two orders of magnitude compared to the single-layer capillary configuration. With further optimization of the fabrication process, the nested tellurite AR-HCF is expected to achieve lower losses, thereby demonstrating substantial potential for applications in mid-infrared (3\u201310\u2009\u03bcm) laser transmission systems.\n                  <\/jats:p>","DOI":"10.1364\/ol.579861","type":"journal-article","created":{"date-parts":[[2026,1,7]],"date-time":"2026-01-07T15:00:15Z","timestamp":1767798015000},"page":"648","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Low-loss tellurite anti-resonant hollow-core fiber with nested capillaries"],"prefix":"10.1364","volume":"51","author":[{"given":"Jun","family":"Zhu","sequence":"first","affiliation":[{"name":"Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"},{"name":"Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziqian","family":"Zhang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"},{"name":"Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengzhen","family":"Liu","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"},{"name":"Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanjie","family":"Chang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"},{"name":"Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1821-2100","authenticated-orcid":true,"given":"Hao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"},{"name":"Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1426-0535","authenticated-orcid":true,"given":"Xusheng","family":"Xiao","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"},{"name":"Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9106-2247","authenticated-orcid":true,"given":"Yang","family":"Xiao","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"},{"name":"Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yantao","family":"Xu","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"},{"name":"Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haitao","family":"Guo","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"},{"name":"Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"285","published-online":{"date-parts":[[2026,1,27]]},"reference":[{"key":"ol-51-3-648-R1","doi-asserted-by":"publisher","first-page":"10768","DOI":"10.1038\/ncomms10768","type":"journal-article","volume":"7","author":"Cha","year":"2016","journal-title":"Nat.
