Conventional soliton (CS) and noise-like pulse (NLP) are two different kinds of pulse regimes in ultrafast fiber lasers, which have many intense applications. In this article, we experimentally demonstrate that the pulse regime of an Er-doped fiber laser could be converted between conventional soliton and noise-like pulse by using fast response saturable absorbers (SA) made from different layers of single-wall carbon nanotubes (CNT). For the monolayer (ML) single-wall CNT-SA, CS with pulse duration of 439 fs at 1560 nm is achieved while for the bilayer (BL) single-wall CNT, NLP at 1560 nm with a 1.75 ps spike and a 98 ps pedestal is obtained. The transition mechanism from CS to NLP is investigated by analyzing the optical characteristics of ML and BL single-wall CNT. The further theoretical simulation illustrates that CNT-SA enables the switching between CS and NLP in anomalous dispersion regime in Er-doped fiber lasers.

碳纳米管可饱和吸收剂的掺Er光纤激光器中产生的传统孤子和类似于噪声的脉冲

常规孤子(CS)和类噪声脉冲(NLP)是超快光纤激光器中的两种不同类型的脉冲方案,其应用非常广泛。在本文中,我们通过实验证明,通过使用由单层碳纳米管(CNT)的不同层制成的快速响应可饱和吸收剂(SA),可以将掺Er光纤激光器的脉冲形式在常规孤子和类似噪声的脉冲之间进行转换。 )。对于单层(ML)单壁CNT-SA,在1560 nm处可获得439 s脉冲持续时间的CS,而对于双层(BL)单壁CNT,在1.60 ps峰值和98 ps的1560 nm处可获得NLP。获得基座。通过分析ML和BL单壁CNT的光学特性,研究了从CS到NLP的转变机理。
