Optics Express, 27(1), 196-201. DOI: 10.1364/OE.27.000196 We report a hybrid process by combining both vapor-phase and solution-doping techniques of rare-earth doped preform fabrication in conjunction with MCVD technique to fabricate highly efficient Tm-doped laser fibers. The proposed fabrication route takes the advantage of co-doping silica with high alumina content through vapor-phase doping process, which is otherwise difficult to achieve using conventional solution doping technique. In addition, by employing the solution doping method, high-purity thulium halide precursors having low vapor pressures at room temperature can be used to dope the fiber core region with high thulium concentrations that is optimized for an efficient two-for-one cross-relaxation process for 79xnm diode pumped thulium-doped fiber laser. Fibers fabricated using the hybrid approach show more homogeneous and flat-top dopant profiles compared with the conventional approach, where both aluminum and thulium are incorporated in the core through solution doping. This will ensure more doped region to take part in the cross-relaxation process. Superior laser performance with a slope efficiency of >70% in the two-micron band has been demonstrated when diode pumped at ~790nm.

Abstract

Data for the paper: Ramírez-Martínez, N. J., Núñez-Velázquez, M., Umnikov, A. A., & Sahu, J. K. (2019). Highly efficient thulium-doped high-power laser fibers fabricated by MCVD. Optics Express, 27(1), 196-201. DOI: 10.1364/OE.27.000196 We report a hybrid process by combining both vapor-phase and solution-doping techniques of rare-earth doped preform fabrication in conjunction with MCVD technique to fabricate highly efficient Tm-doped laser fibers. The proposed fabrication route takes the advantage of co-doping silica with high alumina content through vapor-phase doping process, which is otherwise difficult to achieve using conventional solution doping technique. In addition, by employing the solution doping method, high-purity thulium halide precursors having low vapor pressures at room temperature can be used to dope the fiber core region with high thulium concentrations that is optimized for an efficient two-for-one cross-relaxation process for 79xnm diode pumped thulium-doped fiber laser.
