Abstract :
We report on the generation of a new kind of nanosecond high-energy square pulses in passively mode-locked Yb-doped fiber laser with all-normal-dispersion ring cavity configuration. The generated square pulses have a triangular spectrum with a 3 dB spectral bandwidth of only 0.18 nm. The square pulses are wave-breaking-free and have pulse energy of 34 nJ at the pump power of 323 mW.
