In response to this problem, we developed a stress coefficient calibration method that combines acoustoelastic and photoelastic effects, establishing a direct correlation between longitudinal wave velocity and stress birefringence. The feasibility and accuracy of the ultrasonic immersion pulse-echo method in capturing the acoustoelastic effect were verified through finite-element simulation, thereby laying a solid foundation for the subsequent experimental design. To realistically replicate the stress state during actual fabrication, we introduced a wide-range composite stress field in samples possessing intrinsic structural stresses through the quenching treatment. Experimental results reveal a clear linear relationship with\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u22650.967 between longitudinal wave velocity and stress birefringence within a stress birefringence range of 0\u201340\u00a0nm\/cm, yielding a stress coefficient of approximately \u22120.43884(m\/s)\/(nm\/cm) with a standard deviation of 0.00965\u00a0(m\/s)\/(nm\/cm). This method eliminates the need for complex mechanical loading and is both non-contact and non-destructive, thereby providing, to our knowledge, a new approach for the non-destructive testing of residual stress and the optimization of manufacturing processes in ultra-low expansion quartz glass.\n                  <\/jats:p>","DOI":"10.1364\/ao.582623","type":"journal-article","created":{"date-parts":[[2026,1,2]],"date-time":"2026-01-02T19:00:10Z","timestamp":1767380410000},"page":"1125","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Stress coefficient calibration from correlating longitudinal wave velocity and stress birefringence in ultra-low expansion quartz glass"],"prefix":"10.1364","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5687-686X","authenticated-orcid":true,"given":"Wenqing","family":"Wei","sequence":"first","affiliation":[{"name":"Southwest University of Science and Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zisheng","family":"Tang","sequence":"additional","affiliation":[{"name":"Southwest University of Science and Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4810-7355","authenticated-orcid":true,"given":"Lingxin","family":"Kong","sequence":"additional","affiliation":[{"name":"Yantai University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingxia","family":"Zhou","sequence":"additional","affiliation":[{"name":"Southwest University of Science and Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifan","family":"Zhu","sequence":"additional","affiliation":[{"name":"Southwest University of Science and Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guojun","family":"Xia","sequence":"additional","affiliation":[{"name":"Hubei Feilihua Quartz Glass Co., Ltd."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hu","family":"Deng","sequence":"additional","affiliation":[{"name":"Southwest University of Science and Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong","family":"Liu","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,1,22]]},"reference":[{"key":"ao-65-4-1125-R1","doi-asserted-by":"publisher","first-page":"1927","DOI":"10.3390\/app14051927","type":"journal-article","volume":"14","author":"Zhu","year":"2024","journal-title":"Appl.
