论文摘要
单壁碳纳米管包裹在硼硝酸盐纳米管中（SWCNT@bnnt）是一种新型纳米材料，具有一维范德华（1d-vdw）异质结构。在本文中，我们证明了SWCNT@bnnt具有增强的光功率耐受性，而原始SWCNT则具有光学饱和吸收特性。在13kW/cm2的光功率强度下，发现SWCNT@bnnt的寿命比SWCNT长2,270倍，可吸收1％降解。使用SWCNT@bnnt作为饱和吸收剂，已经实现了高重复率的短载模式锁定激光器。我们已经表明，用1D-VDW异质结构制造纳米材料的技术可以修改和增强封装的纳米材料的光学特性。
Single-walled carbon nanotube encapsulated in boron nitrite nanotube (SWCNT@BNNT) is a novel nanomaterial with a one-dimensional van der Waals (1D-vdW) heterostructure. In this paper, we demonstrated that the SWCNT@BNNT has an enhanced optical power tolerance compared to that of the pristine SWCNT while exhibiting an optical saturable absorption properties. Under optical power intensity of 13kW/cm2, the lifetime of the SWCNT@BNNT is found to be 2,270 times longer than SWCNT for 1% degradation in absorbance. A short-cavity mode-locked laser with a high repetition rate of 1 GHz has been realized using the SWCNT@BNNT as the saturable absorber. We have shown that the technique of fabricating nanomaterial with a 1D-vdW heterostructure can modify and enhance the optical properties of the encapsulated nanomaterials.
