Paper Abstract

The performances of diode-pumped 2.7?m fiber laser have been studied. From the population inversion estimated for a fluorozircoaluminate (AZF) glass with different ErF3 doping, a higher gain was expected for a higher ErF3 doping. The laser performances were improved by adjusting fiber length. Maximum output power of 18.5mW and slope efficiency of 7% were obtained by using 10mol% ErF3 doped, 25mm long AZF fiber in the 800nm pumping. A cw lasing was achieved by diode-pumping at 0. 98pm and the effect of Yb3+ sensitization was discussed to improve the performance.
