文摘We report the experimental observation of passive harmonic mode locking of gain-guided solitons in erbium-doped fiber lasers either made of purely normal dispersion fibers or operating in the net normal cavity dispersion regime. Harmonic-2 and harmonic-3 mode locking states of the gain-guided solitons with supermode suppression larger than 35 dB have been obtained.
