Graphdiyne (GDY) is a novel 2D all‐carbon nanomaterial, which has an intransic band gap, strong light–matter interaction, and large optical absorption in the infrared region, indicating that it has great potential in the field of mid‐infrared ultrafast photonics. Here, a Z‐scan method is used to demonstrate the broadband and strong nonlinear optical (NLO) response of GDY, and its performance in the application of mid‐infrared ultrafast photonics is explored for the first time. The experimental results demonstrate that its nonlinear parameters are superior to the current mainstream 2D materials. By using GDY as the saturable absorber, stable mode‐locked and chaotic pulses are obtained at 1.5 µm. In addition, as a mode‐locked device of thulium‐doped fiber laser, high‐power pulse output is obtained at 2 µm band. This work shows that GDY, as a promising NLO material, has opened up a new pathway for the development of near‐ and mid‐infrared photonic devices.

Graphdiyne作为有前景的中红外非线性光学材料,用于超快光子学

石墨二炔(Graphyyne,GDY)是一种新型的二维全碳纳米材料,具有跨跃带隙,强的光物质相互作用以及在红外区域的大光吸收,这表明它在中红外超快光子学领域具有巨大的潜力。 。在这里,Z扫描法用于证明GDY的宽带和强非线性光学(NLO)响应,并且首次探索了其在中红外超快光子学应用中的性能。实验结果表明,其非线性参数优于目前主流的二维材料。通过将GDY用作可饱和吸收体,可以在1.5 µm处获得稳定的锁模脉冲和混沌脉冲。此外,作为掺th光纤激光器的锁模装置,可以在2 µm波段获得高功率脉冲输出。这项工作表明,GDY,
