An electronically wavelength-tunable mode-locked fiber laser using an all-fiber acoustooptic tunable filter

Abstract

We have demonstrated a novel scheme of a continuously wavelength-tunable and passively mode-locked fiber laser by using the sliding frequency effect of an all-fiber acoustooptic tunable filter. Stable and nearly transform-limited pulses of 800-fs pulsewidth were produced with this laser scheme for a wavelength tuning range of 17 mm at around 1550 mm.
