摘要

A mode-locked erbium doped fiber laser (EDFL) is demonstrated using the vanadium oxide (V2O5) material as a saturable absorber (SA).The V2O5 based SA is hosted into poly ethylene oxide film and attached on fiber ferule in the laser cavity.It shows 7％ modulation depth with 71 MW/cm2 saturation intensity.By incorporating the SA inside the EDFL cavity with managed intra-cavity dispersion,ultrashort soliton pulses are successfully generated with a full width at half maximum of 3.14 ps.The laser operated at central wavelength of 1559.25nm and repetition frequency of 1 MHz.
