Optical Tuning of Second-Order Optical Nonlinearity in Transition Metal Dichalcogenides

We show that the optical depopulation of conduction band electrons, close to high-symmetry K/K' points, modulates the contribution of interband electronic transitions in the second-order dielectric susceptibility of transition metal dichalcogenides, enabling ultrafast tuning of nonlinear processes.
