Abstract :
Investigation of a self-sweeping fiber laser with regular dynamics shows that the phases of modes generated with different pulses are not random. A superposition of 18 consequent laser pulses inside an external ring fiber cavity highlights their coherent combining into a train of nanosecond pulses.
