Wavelength-tunable picosecond soliton fiber laser with topological insulator : Bi2Se3 as a mode locker
Based on the open-aperture Z-scan measurement, we firstly uncovered the saturable absorption property of the topological insulator (TI): Bi2Se3. A high absolute modulation depth up to 98% and a saturation intensity of 0.49 GWcm−2 were identified. By incorporating this novel saturable absorber materi...
