Solar-pumped tem00 mode nd:yag laserAtomic and Molecular Physics, and OpticsThese research projects were funded by the Science and Technology Foundation of Portuguese Ministry of Science (PTDC/FIS/103599/2008 and PTDC/FIS/122420/2010), Technology and Higher Education (FCT-MCTES).Here we show a significant advance in solar-pumped laser beam brightness by utilizing a 1.0 m diameter Fresnel lens and a 3 mm diameter Nd:YAG single-crystal rod. The incoming solar radiation is firstly focused by the Fresnel lens on a solar tracker. A large aspheric lens and a 2D-CPC concentrator are then combined to further compress the concentrated solar radiation along the thin laser rod within a V-shaped pumping cavity. 2.3 W cw TEM00 (M2 ? 1.1) solar laser power is finally produced, attaining 1.9 W laser beam brightness figure of merit, which is 6.6 times higher than the previous record. For multimode operation, 8.1 W cw laser power is produced, corresponding to 143% enhancement in collection efficiency.CeFITec – Centro de Física e Investigação TecnológicaDF – Departamento de FísicaRUNLiang, DaweiAlmeida, Joana2021-01-07T23:43:43Z2013-10-212013-10-21T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article6application/pdfhttp://hdl.handle.net/10362/109913engPURE: 27379484https://doi.org/10.1364/OE.21.025107info:eu-repo/semantics/openAccessreponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAP2024-05-22T17:49:45Zoai:run.unl.pt:10362/109913Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-28T17:21:03.482564Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse |
