Ultrafast fiber lasers at 1560 nm and 1932 nm modulated by WC nanoparticles and d-shaped fibers

Organic dye-loaded reduced titanium dioxide as a broadband saturable absorber for ultrafast fiber lasers

“… 17 ) and WCNs. 18 However, the investigation of new materials for use as SAs is still in early stages. Therefore, it is necessary to explore novel materials as alternative SAs with excellent nonlinear optical properties for achieving mode-locked ultrashort pulse lasers.…”
