Introduction

Giant and ultrashort pulse operations of laser devices play an important role in both physics and engineering. The Q-switched operation and mode-locked pulses from fibre lasers have been being of great interests since single-mode fibre lasers were developed. In this paper we report (1) the first observation of repetitive self-pulsing of a fibre laser, (2) the first demonstration of an all-fibre self-pulsed and diode-locked fibre laser, and (3) a simultaneously Q-switched and mode-locked fibre laser modlulated at the Q-switching frequency.
