Abstract

Abstract: We experimentally demonstrate a wavelength-tunable passively mode-locked Yb-doped all-normal-dispersion fiber laser by exploiting a high-birefringence Sagnac fiber loop as a flexible filter. The wavelength of pulses is controlled by properly rotating the polarization controllers in a Sagnac loop. The spectrum of output pulses could be shifted by up to 15 nm at a repetition rate of 18 MHz. Output power of more than 43 mW at pulse durations below 11.4 ps is achieved at the central wavelength of 1035 nm. The pulse temporal frequency and output power change slightly over the tunable range.
