Abstract

The use of an unidirectional auxiliary pump at approximately 1600 nm in conjunction with a 980 nm primary pump for Ytterbium (Yb3+)-sensitized-Thulium (Tm3+)-doped single mode silica fiber (YTDF) is found to be very effective to activate the most significant resonance energy transfer from Yb3+ to Tm3+, in order to obtain significant emission in the near-infrared. The resulting laser performance of the YTDF at 1874 nm is reported here. The influence of the Tm3+/Yb3+ concentration, their relative proportions and the host glass composition on the lasing efficiency has also been investigated to optimize the fiber parameters for maximum laser output power.
