·制备Co2+：ZNS薄膜超细纤维的方法是电子束蒸发技术。·接近的被动锁模光纤激光器具有很高的稳定性。·基于Co2+：ZNS薄膜的微光纤在色散管理中有很好的应用。报道了不同平均色散条件下，Co2+：ZNS薄膜可饱和吸收体(SAS)被动锁模全光纤激光器中孤子脉冲的特性。采用电子束蒸发技术制备了Co2+：ZNS薄膜超微纤维薄膜。通过将薄膜插入到激光腔中，获得了中心波长为1565 nm、3分贝带宽为5 nm的常规孤子。信噪比(SNR)超过57分贝，证明了出色的输出稳定性。通过适当的色散管理，还获得了带宽为28 nm的3分贝耗散孤子。结果表明，基于微光纤的Co2+：ZNS薄膜SA在超快光电子学器件中具有良好的光学特性。
• The method of preparing microfiber-based Co 2+ :ZnS-film SAs is electron beam evaporation technology. • The approached passively mode-locked fiber laser exhibits a high stability. • The microfiber-based Co 2+ :ZnS-film SAs have a good application in the dispersion management. We report on the characteristics of soliton pulses in the passively mode-locked all-fiber lasers containing the microfiber-based Co 2+ :ZnS-film saturable absorbers (SAs) under different average dispersion. The microfiber-based Co 2+ :ZnS-film SAs are fabricated by electron beam evaporation technology. The conventional soliton (CS) centered at 1565 nm with a 3-dB bandwidth of 5 nm is obtained by inserting the film into the laser cavity. The signal-to-noise ratio (SNR) is over 57 dB, which confirms excellent output stability. Via appropriate dispersion management, dissipative soliton (DS) with a 3-dB bandwidth of 28 nm is also obtained. Our results verify that the microfiber-based Co 2+ :ZnS-film SA exhibits excellent optical characteristics in ultra-fast photonics devices.
