Diode-pumped cw lasing at 2.71, 2.75, and 2.78 {mu}m from an erbium-doped ZBLAN single-mode fiber is reported for the first time. A threshold of 4 mW absorbed power at 792 nm was obtained for the 2.71 {mu}m transition. 3% slope efficiency was obtained with an 80% reflecting output mirror. cw lasing was also observed from the fiber when a tunable pump was scanned across most of the {sup 4}{ital I}{sub 15/2}{r arrow}{sup 4}{ital I}{sub 9/2} absorption band. cw lasing observed when pumping around 820 nm indicates that excited-state absorption of the pump from the {sup 4}{ital I}{sub 13/2} may not be necessary for cw operation. However, excited-state absorption of the pump around 810 nm from the {sup 4}{ital I}{sub 11/2} may limit performance.
