Recently, two-dimension transition metal carbides, carbonitrides, and nitrides called MXenes have attracted huge attention due to their outstanding physical properties in various fields. 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 Ti 3 C 2 T x 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.

激光技术中MXene的非线性光学

近年来，二维过渡金属碳化物，碳氮化物和称为MXene的氮化物由于在各个领域的出色物理性能而备受关注。在这里，我们重点介绍了MXene作为激光技术中非线性光学材料的巨大潜力，其中包括超快激光脉冲生成，基于四波混合的激光频率调制以及具有时间反转对称性破坏的光子二极管。重点放在无源锁模飞秒激光技术中的金属MXene饱和吸收剂的宽光谱适用性上，以允许在可见到中红外范围内工作。Z扫描分析表明，Ti 3 C 2 T x MXene具有较大的非线性光学吸收系数和负的非线性折射率，并且值得注意的是，它还具有较高的光致损伤阈值，非线性透射率提高了50％。MXene / C 60胶粘剂
