Efficient diode-pumped CW and <i>Q</i> -switched single-mode fibre laser

Abstract

We report the efficient operation an Nd3+-doped silica single-mode fibre laser pumped by a GaAlAs laser diode. A CW output power in excess of 1 mW at 1.088 μm has been obtained with a slope efficiency of 33%. Q-switched operation of this device is also reported.
