Ultrasmall 2D NbSe2 based quantum dots used for low threshold ultrafast lasers

Ultrasmall NbSe2 quantum dots (QDs) with an average diameter of 2.68 nm were successfully fabricated and investigated. By employing the NbSe2 quantum dots (QDs) as a saturable absorber, highly stable ultrafast laser pulse trains with a duration of 765 fs or 380 ps were successfully generated from mo...
