Abstract
We investigated the ~2 m lasing performance of Tm
3+
doped tellurite microstructure fiber pumped by an Er
3+
doped silica fiber laser operating at 1 560 nm. The microstructure fibers consisting of a solid core surrounded by six air holes were fabricated by using a rod-in-tube method. A maximum unsaturated power of 9 mW laser operating at ~1 872 nm was obtained in a Tm
3+
doped 2.8 cm long microstructure fiber with the slope efficiency of ~6.53% and the threshold power of ~200 mW. The results indicate that the Tm
3+
doped tellurite microstructure fiber is a promising material for the compact 2 m fiber laser.
