Suppression of self-pulsing behavior in erbium-doped fiber lasers with resonant pumping: experimental results

Experimental results are presented showing that resonant pumping can significantly improve the stability of erbium-doped fiber lasers. In particular, it is observed that an erbium fiber laser that exhibits sustained spiking behavior when pumped at 980 nm will revert to stable cw operation when pumped at 1510 nm.
