An ultralow-repetition-rate, all-normal-dispersion fiber laser is proposed which is passively mode-locked by an SESAM (semiconductor saturable absorber mirror) with ultra long cavity length and high concentration single mode ytterbium-doped fiber. The central wavelength, repetition rate, average power and energy of a single output pulse are 1 064 nm, 281.5 kHz, 11 mW and 39 nJ, respectively. A band-pass filter is employed in the cavity to stabilize the central wavelength and realize self-start operation. The laser operates stably and has no Q-switching instabilities, which greatly reduces the damage probability of the SESAM.
