Black phosphorus (BP) ranks among the most promising saturable absorber materials for ultrafast pulse generations at 2 μm. However, the easy-to-degrade characteristic of BP seriously limits the long-term operation of ultrafast fiber lasers and hence becomes a bottleneck for its relevant practical applications. In this paper, a modified electrochemical delamination exfoliation process was explored to produce high-performance, large-size, and oxidation-resistant BP nanosheets, where BP nanosheets in high yield with evenly coated tetra-n-butyl-ammonium organics by precisely controlling the intercalation chemistry can be obtained. A mode-locked Tm/Ho co-doped fiber laser with high temporal stability and long-term operation capability was demonstrated based on the innovatively fabricated BP saturable absorber. The self-starting mode-locking operation featuring a high signal-to-noise ratio of 58 dB and long-term stability has been verified for at least 3 weeks, which indicates the successful passivation of the employed synthesis method. These results fully indicated that passivated BP is an efficient candidate in a 2 μm range ultrafast photonic field, which will promote the ultrafast optical application of BP and also other infrared photonic and photoelectronic devices.

耐氧化的黑色磷可在2μmTm / Ho掺杂的光纤激光器中实现高度环境稳定的超快脉冲生成
黑磷（BP）在2μm的超快脉冲产生中，是最有前途的可饱和吸收剂材料之一。但是，BP易于降解的特性严重限制了超快光纤激光器的长期运行，因此成为其相关实际应用的瓶颈。在本文中，经修饰的电化学剥离剥离工序进行了探讨，以生产高性能，大尺寸，并且耐氧化BP纳米片，其中以高收率BP纳米片与均匀涂四Ñ通过精确控制插层化学可制得丁基丁基铵有机物。基于创新制造的BP饱和吸收体，证明了具有高时间稳定性和长期运行能力的锁模Tm / Ho共掺杂光纤激光器。具有58 dB的高信噪比和长期稳定性的自启动锁模操作已被验证至少3周，这表明所采用的合成方法已成功钝化。这些结果充分表明，钝化BP是2μm范围的超快光子领域的有效候选者，这将促进BP以及其他红外光子和光电子器件的超快光学应用。
