By employing a dual Nd:YVO\u2084 crystal pumping configuration in combination with a Z\u2011shaped cavity design, the thermal lensing effect in the laser crystal was significantly suppressed. Consequently, the maximum injected pump power was increased from 40\u2009W in a single-crystal scheme to 130\u2009W, yielding 18.4\u2009W of fundamental laser at 1342\u2009nm. With the fundamental beam tightly focused to a 65\u00a0\u03bcm waist radius on the diamond, continuous-wave Raman output at 1634\u00a0nm was achieved with a power of 1.46\u00a0W, representing the highest power reported. The device also exhibits good beam quality (M\n                    <jats:sup>2<\/jats:sup>\n                    \u00a0&lt;\u00a01.3) and power stability (RMS\u00a0&lt;\u00a02% over 1\u2009hour). Numerical simulations further indicate that by increasing the local pump density within the Raman medium and optimizing the output coupling ratio, the output power can potentially be scaled to the 10\u2009W level.\n                  <\/jats:p>","DOI":"10.1364\/ol.599947","type":"journal-article","created":{"date-parts":[[2026,5,18]],"date-time":"2026-05-18T14:00:10Z","timestamp":1779112810000},"page":"3249","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Continuous-wave watt-level diamond Raman laser at 1634\u2009nm by intracavity pumping with dual Nd:YVO\n                    <sub>4<\/sub>\n                    crystals"],"prefix":"10.1364","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-0248-5927","authenticated-orcid":true,"given":"Houjie","family":"Ma","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ypx8c21","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fengying","family":"Ma","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ypx8c21","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaobo","family":"Mi","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ypx8c21","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2113-5839","authenticated-orcid":true,"given":"Xun","family":"Yang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ypx8c21","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5817-1369","authenticated-orcid":true,"given":"Liwen","family":"Cheng","sequence":"additional","affiliation":[{"name":"Yangzhou University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8116-4378","authenticated-orcid":true,"given":"Yongsheng","family":"Hu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ypx8c21","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chongxin","family":"Shan","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ypx8c21","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijun","family":"Wang","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,5,29]]},"reference":[{"key":"ol-51-11-3249-R1","doi-asserted-by":"publisher","first-page":"2416188","DOI":"10.1080\/26941112.2024.2416188","type":"journal-article","volume":"4","author":"Cai","year":"2024","journal-title":"Funct.
