Here we highlight the enormous potential of MXenes as nonlinear optical materials in the laser technologies, which includes ultrafast laser pulse generation, laser frequency modulation based on four-wave mixing, and photonic diodes with time reversal symmetry breaking. Emphasis is placed on the wide spectral applicability of metallic MXene saturable absorbers in passively mode-locked femtosecond laser technologies, allowing for operation in the visible to mid-infrared range. The Z-scan analysis reveals that Ti3C2Tx MXene has a large nonlinear optical absorption coefficient and a negative nonlinear refractive index, and notably it also possesses the higher threshold for light-induced damage with 50% increase in nonlinear transmittance. The MXene/C60 stacked modules enable the achievement of nonreciprocal transmission of laser pulses for photonic rectification. We strongly believe that MXenes will play a significant role in advanced laser technologies such as optical information processing, molecular spectroscopy, and micromachining, while providing many insightful electro-optical applications. ？ 2020 The Author(s).
