Emission Wavelength Limits of a Continuous-Wave Thulium-Doped Fiber Laser Source Operating at 1.94 µm, 2.09 µm or 2.12 µm

open access: yesPhotonics
We present a thulium-doped single-oscillator monolithic fiber laser emitting successively at three wavelengths, especially at unusual long wavelengths as 2.09 µm and even at 2.12 µm.

Outstanding CO2 Photoreduction in Single‐Atom Thulium Modified Carbon Nitride

open access: yesAdvanced Science
CO2 reduction photocatalysts are favorable for obtaining renewable energy. Enriched active sites and effective photogenerated‐carriers separation are keys for improving CO2 photo‐reduction. A thulium (Tm) single atom tailoring strategy introducing carbon

Thulium fiber lasers with longitudinally modified concentration

open access: yesHigh Power Laser Science and Engineering
High-power fiber lasers generate local heat load extremes during their operation, which increase the fiber temperature and lead to adverse thermal effects, such as transverse mode instability or cladding/coating thermal damage.

Theoretical Calculations and Experimental Investigation of Separation of Dy3+, Er3+, Tm3+ and Yb3+ by Cascade Extraction in TOGDA–Kerosene/Hydrochloric Acid System

open access: yesSeparations
The hot spot extraction agent N,N,N′,N′-tetraoctyl-3-oxoglutaramide (TODGA) has the advantages of novelty, high efficiency and environmental protection in the separation of rare earths by tandem extraction.
