Single-mode room-temperature cw laser emission on the [sup 6]H[sub 13/2]→[sup 6]H[sub 15/2] 2.9 μm phonon terminated electronic transition of Dy[sup 3+] is demonstrated. The maximum output power of 0.275 W was generated at a slope efficiency of 4.5% (with respect to the absorbed pump power) when a Dy[sup 3+]-doped ZBLAN fiber laser was tandem pumped with the ∼1100 nm output from a diode-cladding-pumped Yb[sup 3+]-doped silica fiber laser. © 2003 American Institute of Physics.

    Abstract. Homogeneity of sol-gel-derived silica was improved by slowing down the drying and aging rate. Single longitudinal mode lasing was achieved in sol-gel silica doped with coumarin 460 dye. The laser linewidth was 1.58 GHz and the output wavelength was at 467 nm.
