Ultra-strong nonlinear optical processes and trigonal warping in MoS2 layers

Ultra-strong nonlinear optical processes and trigonal warping in MoS2 layers

Harmonic generation is a nonlinear optical process occurring in a variety of materials; the higher orders generation is generally less efficient than lower orders. Here, the authors report that the third-harmonic is thirty times stronger than the second-harmonic in monolayer MoS2.
