2.0 μm Ultra Broadband Emission from Tm<sup>3+</sup>/Ho<sup>3+</sup> Co-Doped Gallium Tellurite Glasses for Broadband Light Sources and Tunable Fiber Lasers

2.0 μm Ultra Broadband Emission from Tm<sup>3+</sup>/Ho<sup>3+</sup> Co-Doped Gallium Tellurite Glasses for Broadband Light Sources and Tunable Fiber Lasers

A flat 2.0 μm ultra broadband emission with a full width at half maximum (FWHM) of 329 nm is achieved in 1 mol.% Tm<sub>2</sub>O<sub>3</sub> and 0.05 mol.% Ho<sub>2</sub>O<sub>3</sub> co-doped gallium tellurite glasses upon the excitation of an 808 nm...
