Two pieces of subsurface layer doped Fe:ZnSe polycrystal are adoptive in a reflective resonator configuration and face-cooled by liquid nitrogen. A maximal Fe:ZnSe laser power of 105\u2005W at a wavelength of 4.1\u2005\u03bcm is achieved upon pumping by ten home-made Er:YAG lasers with fiber coupled output working at a frequency of 250\u2005Hz and a pulse duration of \u223c420\u2005\u03bcs. Corresponding to the maximum Fe:ZnSe laser power, the optical\u2013optical efficiency and slope efficiency with respect to the absorbed pump power are 43% and 44% respectively. The beam quality factor <jats:italic>M<\/jats:italic><jats:sup>2<\/jats:sup> is measured to be 3.4. To the best of our knowledge, it is the highest output average power of an Fe:ZnSe laser reported.<\/jats:p>","DOI":"10.1364\/ol.525052","type":"journal-article","created":{"date-parts":[[2024,5,29]],"date-time":"2024-05-29T19:00:19Z","timestamp":1717009219000},"page":"3476","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["High average power (105\u2005W) Fe:ZnSe laser pumped by radiation of laser diode side-pumped Er:YAG lasers"],"prefix":"10.1364","volume":"49","author":[{"given":"Yingchen","family":"Wu","sequence":"first","affiliation":[{"name":"Nanjing University of Science and Technology"},{"name":"Institute of Applied Electronics"},{"name":"The Graduate School of China Academy of Engineering Physics"},{"name":"National Key Laboratory of Science and Technology on Advanced Laser and High Power Microwave"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Zhou","sequence":"additional","affiliation":[{"name":"Institute of Applied Electronics"},{"name":"National Key Laboratory of Science and Technology on Advanced Laser and High Power Microwave"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sikun","family":"Zhou","sequence":"additional","affiliation":[{"name":"Institute of Applied Electronics"},{"name":"National Key Laboratory of Science and Technology on Advanced Laser and High Power Microwave"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huaijin","family":"Ren","sequence":"additional","affiliation":[{"name":"Institute of Applied Electronics"},{"name":"National Key Laboratory of Science and Technology on Advanced Laser and High Power Microwave"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Song","family":"Zhang","sequence":"additional","affiliation":[{"name":"The Graduate School of China Academy of Engineering Physics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingbin","family":"Wei","sequence":"additional","affiliation":[{"name":"Institute of Applied Electronics"},{"name":"National Key Laboratory of Science and Technology on Advanced Laser and High Power Microwave"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianli","family":"Shang","sequence":"additional","affiliation":[{"name":"Institute of Applied Electronics"},{"name":"National Key Laboratory of Science and Technology on Advanced Laser and High Power Microwave"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weimin","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Applied Electronics"},{"name":"National Key Laboratory of Science and Technology on Advanced Laser and High Power Microwave"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingyang","family":"Leng","sequence":"additional","affiliation":[{"name":"Institute of Applied Electronics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenlin","family":"Dai","sequence":"additional","affiliation":[{"name":"Institute of Applied Electronics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayu","family":"Yi","sequence":"additional","affiliation":[{"name":"Institute of Applied Electronics"},{"name":"National Key Laboratory of Science and Technology on Advanced Laser and High Power Microwave"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun","family":"Tang","sequence":"additional","affiliation":[{"name":"Institute of Applied Electronics"},{"name":"National Key Laboratory of Science and Technology on Advanced Laser and High Power Microwave"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Chen","sequence":"additional","affiliation":[{"name":"Nanjing University of Science and Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2024,6,12]]},"reference":[{"key":"ol-49-12-3476-R1","doi-asserted-by":"publisher","first-page":"1720","DOI":"10.1364\/OL.24.001720","volume":"24","author":"Adams","year":"1999","journal-title":"Opt.
