Yb- and Er-doped fiber laser Q-switched with an optically uniform, broadband WS(2) saturable absorber
We demonstrate a ytterbium (Yb) and an erbium (Er)-doped fiber laser Q-switched by a solution processed, optically uniform, few-layer tungsten disulfide saturable absorber (WS(2)-SA). Nonlinear optical absorption of the WS(2)-SA in the sub-bandgap region, attributed to the edge-induced states, is ch...
