The unique thickness- and composition-dependent properties of two-dimensional Transition Metal Dichalcogenides (TMDs) afford opportunities to a wide range of applications, as reviewed in [1]. Among the diverse methods to fabricate TMDs, redox exfoliation offers features critical to composite, coating and ink technologies, including low cost, low-energy, and a general framework for exfoliating TMDs from Groups IV, V, VI, and VII. Nonlinear (NL) optical absorption is a relevant effect in TMDs with potential applications in multiphoton microscopy, fluorescence imaging and optical limiting. For instance, two-photon absorption (TPA) saturation in MoS2 was reported in [2]. On the other hand, NL refraction may be exploited for all-optical switching and optical processing.
