Vanadium carbide (V₂C), a member of the MXene family, promises numerous possibilities in ultrafast laser technology with substantial applications in various optical industries. In this work, MXene V₂C was deposited onto a tapered fiber using the drop-casting technique and incorporated into a thulium/holmium doped fiber laser cavity for generating mode-locked outputs in the 2.0 µm region. The fabricated SA exhibited nonlinear optical properties such as saturation intensity and modulation depth of 2.07 MW/cm² and 7.57%, respectively. The findings of the mode-locked characteristics showed a central wavelength of 1937 nm with a signal-to-noise ratio (SNR) of 73 dB. Correspondingly, the laser-generated mode-locked pulses with output power, pulse energy, and peak power of 2.71 mW, 235.2 pJ, and 0.14 kW, respectively. The results suggest that the mode-locked laser obtained based on the MXene V₂C could be applied to the field of photonics.

碳化钒 (V ₂ C) 是 MXene 家族的一员，有望在超快激光技术中提供多种可能性，并在各种光学行业中得到大量应用。在这项工作中，MXene V ₂ C 使用滴铸技术沉积在锥形光纤上，并结合到掺铥/钬光纤激光腔中，以在 2.0 µm 区域产生锁模输出。制成的SA表现出非线性光学特性，例如饱和强度和2.07 MW / cm ^2的调制深度和 7.57%，分别。锁模特性的结果显示中心波长为 1937 nm，信噪比 (SNR) 为 73 dB。相应地，激光产生的锁模脉冲的输出功率、脉冲能量和峰值功率分别为 2.71 mW、235.2 pJ 和 0.14 kW。结果表明，基于MXene V ₂ C获得的锁模激光器可以应用于光子学领域。
