By implementing an advanced doped fiber\n\t\t\t\t\tdesign and a dual-stage precision thermal control system, for the\n\t\t\t\t\tfirst time, we demonstrate a fusion-spliced DBR fiber laser\n\t\t\t\t\tincorporating an 8-mm Yb-doped fiber that achieves &gt;2\u2009nm\n\t\t\t\t\tmode-hop-free continuous tuning across an extended temperature range\n\t\t\t\t\tof \u221220\u2009\u00b0C to 175\u2009\u00b0C. The\n\t\t\t\t\tintegration of a piezoelectric transducer (PZT) tuning mechanism\n\t\t\t\t\tenables rapid frequency adjustment with a 10-GHz tuning bandwidth.\n\t\t\t\t\tRegarding noise performance, the combination of ultra-stable\n\t\t\t\t\ttemperature regulation and a specially designed low-noise laser diode\n\t\t\t\t\t(LD) pump driver achieves remarkable improvements: the intrinsic\n\t\t\t\t\tlinewidth is reduced from 3\u2009kHz (free-running) to\n\t\t\t\t\t800\u2009Hz, while the intensity noise exhibits suppressed\n\t\t\t\t\trelaxation oscillations below \u2212137\u2009dBc\/Hz. These\n\t\t\t\t\tperformance advancements establish this laser system as an exceptional\n\t\t\t\t\toptical source for precision microwave measurements based on Rydberg\n\t\t\t\t\tatom spectroscopy.<\/jats:p>","DOI":"10.1364\/ol.566497","type":"journal-article","created":{"date-parts":[[2025,7,16]],"date-time":"2025-07-16T12:59:29Z","timestamp":1752670769000},"page":"5045","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A 2-nm mode-hop-free tunable 1018-nm DBR single-frequency low-noise fiber laser"],"prefix":"10.1364","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-6618-7425","authenticated-orcid":true,"given":"Pan","family":"Li","sequence":"first","affiliation":[{"name":"Institute of Mechanics, Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linfeng","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Mechanics, Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Xiao","sequence":"additional","affiliation":[{"name":"Nanchang University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaiming","family":"Cao","sequence":"additional","affiliation":[{"name":"Institute of Mechanics, Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heshan","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Mechanics, Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziren","family":"Luo","sequence":"additional","affiliation":[{"name":"Institute of Mechanics, Chinese Academy of Sciences"},{"name":"University of Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"285","published-online":{"date-parts":[[2025,8,10]]},"reference":[{"key":"ol-50-16-5045-R1","doi-asserted-by":"publisher","first-page":"052515","DOI":"10.1103\/PhysRevA.83.052515","volume":"83","author":"Mack","year":"2011","journal-title":"Phys.
