Paper Abstract

We report on the construction of a pulse-pumped fiber laser using highly doped gain fiber within a ring-shaped all-fiber resonator. The pump laser is pulse modulated and coupled into a segment of highly doped Erbium doped fiber. The ring cavity is close-looped in an all-fiber manner. The pulsed-lasing in kHz repetition rate down to single-shot operation are tunable by pulsed-modulation of the pump laser and tuning of an intracavity variable optical coupler. The lasing power increases for a higher pump pulse energy and repetition rate which sets the limit of the output pulse energy. We measure the time-domain characteristics of the lasing pulses and analyze the dynamical property of the pulsed-pumping process theoretically based on time-dependent rate equation.
