“…The optical core device that replaces SESAMs in the passive mode-locking technology is saturable absorbers (SAs), [25][26][27] which is a new generation of key optical devices based on nanomaterials. The SA materials mainly rely on graphene, [28,29] black phosphorus, [30,31] transition metal sulfide, [32,33] and topological insulator (TI), [34,35] etc. Those materials have the application prospects in the field of nonlinear optics.…”

Topological insulator materials, including Bi2Te3, Sb2Te3, Sb2Te3 and Bi2Se3, have attracted some attention due to their narrow band gap, high carrier mobility, wide spectral absorption range and other characteristics. Compared with the traditional topological insulator composed of two elements, the new multi-compound topological insulator material can integrate the physical advantages of each element, which is helpful to build an experimental platform with rich physical properties. In this work, the nonlinear optical characteristics of the quaternary material BiSbTeSe2 is reported in the erbium-doped fiber laser. Using the BiSbTeSe2 as a saturable absorber material, the passive Q-switched and mode-locked fiber lasers are achieved. The pulse duration and SNR of the Q-switched fiber laser are 854 ns and 70 dB, respectively. Meanwhile, the pulse duration and SNR of the mode-locked fiber laser are 259 fs and 87.75 dB, respectively. This work proves that the BiSbTeSe2 has a considerable application prospect as a saturable absorber in fiber lasers, and provides a new reference for the selection of high-performance saturable absorber materials.

“…Last two decades, the interest on demonstration of a passively pulsed fiber laser is increasing dramatically due to its highly fa-vorable advantages over the active techniques [1][2][3][4][5]. The key ele-ment to generate passively light pulses is saturable absorber (SA) [6,7] Therefore, this research increment on passively pulsed fiber laser has consequently raised the attention of the researcher on proposing simple and elective methods to fabricate the satura-ble absorbers.…”

A passively pulsed fiber laser using saturable absorbers such as graphene has been increased dramatically in recent years. Up to now, researchers have been proposed many methods to fabricate graphene saturable absorber such as (evanescent coupling structure, electrochemical exfoliation, and mechanical exfoliation) for light pulse generation in a fiber laser. However, each of these methods has got some limitations which reduce the saturable absorber performance and restrict its range of applications. In this paper, we propose a simple but very efficient fabrication way of graphene saturable absorber by converting graphene Nano powder into a thin film using polyvinyl alcohol (PVA) as a host material. The fabricated film can then be easily sandwiched between two fiber pigtails and inserted inside the laser cavity to form the saturable absorber. when compared with other methods, this method is much preferable because it provides saturable absorber with combat structure, maximum interaction area, reasonable insertion loss, polarization insensitive, controllable concentration, and safe to handle. The fabricated graphene saturable absorber in this paper was characterized and found to have a uniform distribution of the graphene nanomaterial in the PVA and have a modulation depth of 6.1% which make it a very promising saturable absorber for ultra-fast fiber laser demonstration.
