Steady photodarkening of thulium alumino-silicate fibers pumped at 1.07  μm: quantitative effect of lanthanum, cerium, and thulium.

Optics letters

Lupi JF, Vermillac M, Blanc W, Mady F, Benabdesselam M, Dussardier B, Neuville DR.
PMID: 27304285
Opt Lett. 2016 Jun 15;41(12):2771-4. doi: 10.1364/OL.41.002771.

By pumping thulium-doped silica-based fibers at 1.07 μm, rapid generation of absorbing centers leads to photoinduced attenuation (PIA). This detrimental effect prevents exploiting laser emissions in the visible and near infrared. We report on the characterization of the PIA...

We report an all solid state laser device producing tunable dual wavelength emission in the near IR region (1060nm, and 1550 nm) by use of an Er/Yb co-doped fiber. Generation of continuous-wave radiation around 630 nm is then demonstrated...
