The mechanical design of the laser beacon, which operates at a depth of 3500 m, is presented, together with the design of the antibiofouling system employed to endure the operational pressure and optimize the operational range, enhancing its functionality and enabling time calibration among multiple towers. A noteworthy innovation central to this development lies in the battery system. This configuration enhances the device's portability, a crucial aspect in underwater operations. The comprehensive design of the laser beacon, encompassing the container housing, the requisite battery system for operation, electronics, and an effective antibiofouling system, is described in this paper. Additionally, this paper presents the findings of the laser beacon's qualification process.}, organization = {Ministerio de Ciencia e Innovación: Programa Estatal para Impulsar la Investigación Científico-Técnica y su Transferencia PID2021-124591NB-B-C41}, organization = {Programa de Planes Complementarios I+D+I ASFAE/2022/023}, organization = {Center for Forestry Research & Experimentation (CIEF) PROMETEO/2020/019}, organization = {Grisolia GRISOLIAP/2021/192}, organization = {GenT CIDEGENT/2018/034, CIDEGENT/2020/049, CIDEGENT/2021/23}, organization = {EU: MSC program, Spain 101025085}, publisher = {MDPI}, keywords = {Neutrino telescope}, keywords = {Time calibration}, keywords = {Laser beacon}, title = {The Neutrino Mediterranean Observatory Laser Beacon: Design and Qualification}, doi = {10.3390/app13179935}, author = {Real, Diego and Sánchez Losa, Agustín and Díaz García, Antonio Francisco and Salesa Greus, Francisco and Calvo, David}, }
