High‐Performance Vanadium Diselenide Nanosheets for the Realization of Compact Pulsed Fiber Lasers

Vanadium diselenide (VSe 2 ), as a transition metal dichalcogenides (TMDC), is an important class of graphene‐like 2D layered materials. It has excellent optical absorption nonlinearity, high thermal damage threshold, and large modulation depth, which can make it to be applied in the field of ultrashort pulse. Here, the nonlinear optical absorption properties of VSe 2 are investigated along with in‐depth exploration of its ultrafast photonics...
