By employing lithium triborate-based resonant\n\t\t\t\t\tcavity with moderate\n\t\t\t\t\tfinesse, we propose an approach for generating efficient SHG in the\n\t\t\t\t\tvisible and ultraviolet spectral ranges without requiring an active\n\t\t\t\t\telectronic servo loop. As a proof of concept, we demonstrate frequency\n\t\t\t\t\tdoubling of a high-power 1064\u00a0nm laser to 532\u00a0nm. To the\n\t\t\t\t\tbest of our knowledge, this is the first implementation of such a\n\t\t\t\t\tcavity featuring a highly reflective coating on one end of this\n\t\t\t\t\tcrystal. This quasi-monolithic design enables simultaneous control of\n\t\t\t\t\tphase matching and cavity resonance solely through temperature\n\t\t\t\t\tadjustment of the nonlinear crystal.<\/jats:p>","DOI":"10.1364\/ao.573796","type":"journal-article","created":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T12:00:10Z","timestamp":1756382410000},"page":"8005","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Free-running operation of a semi-monolithic LBO-based resonant cavity for high-power continuous-wave second-harmonic generation"],"prefix":"10.1364","volume":"64","author":[{"given":"S\u00e9bastien","family":"Vidal","sequence":"first","affiliation":[{"name":"ALPhANOV, Centre Technologique Optique et Laser"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Val\u00e9rian","family":"Freysz","sequence":"additional","affiliation":[{"name":"ALPhANOV, Centre Technologique Optique et Laser"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Damien","family":"Bonaudo","sequence":"additional","affiliation":[{"name":"ALPhANOV, Centre Technologique Optique et Laser"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dominique","family":"Lupinski","sequence":"additional","affiliation":[{"name":"Cristal Laser"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc","family":"Castaing","sequence":"additional","affiliation":[{"name":"ALPhANOV, Centre Technologique Optique et Laser"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"285","published-online":{"date-parts":[[2025,9,15]]},"reference":[{"key":"ao-64-27-8005-R1","doi-asserted-by":"crossref","DOI":"10.1017\/CBO9780511606502","volume-title":"Compact Blue Green Lasers","author":"Risk","year":"2003"},{"key":"ao-64-27-8005-R2","first-page":"JtuD115","article-title":"Fiber-laser-pumped Ti:sapphire laser","volume-title":"Conference on Lasers and Electro-Optics","author":"Samanta","year":"2010"},{"key":"ao-64-27-8005-R3","doi-asserted-by":"publisher","first-page":"851","DOI":"10.1364\/OL.37.000851","volume":"37","author":"Li","year":"2012","journal-title":"Opt.
