Abstract

Data supports the paper: Norberto J. Ramirez-Martinez, M. Nunez-Velazquez, and J. K. Sahu Study on dopant concentration ratio in thulium-holmium doped silica fibers for lasing at 2.1µm Optics Express https://doi.org/10.1364/OE.397855 We present the fabrication and laser performance of thulium-holmium co-doped silica fibers when cladding pumped at ~790 nm. By using the hybrid gas phase-solution doping process in conjunction with the MCVD preform fabrication technique, the doping concentration and the Tm:Ho ratio were varied to study the energy transfer efficiency from Tm3+ to Ho3+. Our study indicates that for a thulium concentration that has resulted in an efficient two-for-one cross relaxation process with 790 nm pumping, and while maintaining a Tm:Ho concentration ratio in the range ~ 10 to 20, the energy transfer efficiency has reached above 75%.
