[IEEE 2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC) - Munich, Germany (2019.6.23-2019.6.27)] 2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC) - Hybrid Ho:YAG Laser with 50W Radially-Polarised Output

摘要： Holmium doped radially polarised lasers operating in the 2.1 μm spectral region are of great interest as they provide benefits of operation in the atmospheric transmission window (2.1-2.25 μm), absorption in transparent polymers, as well as the materials processing benefits that are beginning to be realised from utilising select higher order modes [1]. We report on the development of a 50W CW radially polarised Ho:YAG laser operating at 2090nm.
