Efficient fiber-laser pumped Ho:LuLiF4 laser
We present results for an efficient Ho:LuLiF4 laser in-band pumped by a cladding-pumped Tm-doped silica fiber laser. The polarized, tunable Tm-doped silica fiber-laser operates at 1938 nm, ideally suited for in-band pumping the 40 mm long weakly-doped (0.

Thulium-doped optical fibers for fiber lasers operating at around 2 µm
Bulletin of the Polish Academy of Sciences Technical Sciences, 2019 The paper deals with spectral and lasing characteristics of thulium-doped optical fibers fabricated by means of two doping techniques, i.e. via a conventional solution-doping method and via a nanoparticle-doping method. The difference in fabrication was the application of a suspension of aluminum oxide nanoparticles of defined size instead of a ...

Battery Energy, Volume 4, Issue 2, March 2025.The effect of reagents on the structure and performance of sodium‐layered oxides has not yet been thoroughly studied. This work explored this factor systematically through in situ high‐temperature XRD. The samples synthesized via MnCO3‐based precursors form the Li2MnO3 phase at evaluated temperature and perform better than those through MnO2‐based ...
