Passively mode locked thulium and thulium/holmium doped fiber lasers using MXene Nb2C coated microfiber

Abstract As a result of the emergence of two-dimensional (2D) materials for various opto-electronics applications, a new class of materials named MXenes have been attracting interests due to their outstanding nonlinear properties. In this work, an MXene niobium carbide (Nb2C) was proposed and demons...
