Fractional thulium lasers are also being used to enhance medication delivery into the skin, potentially leading to clearer skin and reduced itchiness. Most of these treatments are covered by ...

The team’s avalanching nanoparticles (ANPs) are sodium yttrium fluoride nanocrystals doped with thulium – and were discovered by the team in 2021. The sensing process uses a laser tuned off-resonance ...

The SWIR E-O combs shows tunable central wavelength and spectral line spacing. Based on the simple combination of the fiber optical parametric amplifier and the Thulium-doped fiber amplifier directly ...

Abstract: We accurately modelled measured TMI thresholds in Tm-doped fiber amplifiers for the first time and with much improved efficiency, demonstrating the significance of the background loss at ∼2 ...
