Abstract

We demonstrate that appropriately designed doped multi-mode fibers provide robust single mode output when used within a fiber laser cavity. Using a novel large mode area fiber we demonstrate record single mode (M2 < 1.2) pulse energies of > 0.5mJ from a Q-switched fiber laser and even higher pulse energies (as high as 0.85mJ) with slightly compromised spatial mode quality (M2 < 2.0). The approach offers significant scope for extending the range of single mode output powers and energies achievable from fiber laser/amplifier systems.
