我们提出了一种混合液体剥离方法，以高效和经济地制备碲化铋纳米晶体。利用z -扫描技术对纳米晶体的非线性透过率进行了表征，实验结果表明纳米晶体具有宽带饱和吸收特性。利用光沉积法将制备好的纳米晶体集成到光纤端面，形成光纤兼容的非线性吸收器件，并利用该器件调制不同腔型的光纤激光器，成功实现脉冲激光的输出。得到了以1562 nm和1068 nm为中心波长的类噪声脉冲和耗散孤子。这些结果证实了混合液体剥离法制备碲化铋纳米晶体的有效性，以及纳米晶体的宽带非线性光学响应和超快光子学应用潜力。
We come up with a hybrid liquid exfoliation method to prepare bismuth telluride nanocrystals efficiently and cost-effectively. The nonlinear transmittance of the nanocrystals has been characterized with Z-scan technique, which can manifest its broadband saturable absorption behavior experimentally. The as-fabricated nanocrystals were integrated onto fiber end facet to form a fiber compatible nonlinear absorption device with optical deposition method, which was then used to modulate the fiber laser with different cavity configurations to deliver pulsed laser successfully. The noise-like pulse and dissipative soliton have been obtained with wavelength centered at 1562 nm and 1068 nm, respectively. These results confirm the effectiveness of the hybrid liquid exfoliation method to prepare bismuth telluride into nanocrystals, and the broadband nonlinear optical response and ultrafast photonics application potential of the nanocrystals.
