Absorption and scattering loss coefficients are determined for 450 nm, 532 nm and 633 nm excitation.2022http://zaguan.unizar.es/record/12439610.1088/1742-6596/2407/1/012032http://zaguan.unizar.es/record/124396oai:zaguan.unizar.es:124396info:eu-repo/grantAgreement/ES/DGA-FEDER/E44-20Rinfo:eu-repo/grantAgreement/ES/MICINN/AEI/PID2020-113080RB-I00info:eu-repo/grantAgreement/ES/MICINN/AEI/PID2020-119636GB-I00info:eu-repo/grantAgreement/ES/MICINN-AEI/RED2018-102331-TJournal of Physics: Conference Series 2407 (2022), 012032 [8 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
