“…In order to achieve stabilized passively mode-locking in fiber lasers, artificial saturable absorbers (SAs) such as the nonlinear polarization rotation [1]- [3], nonlinear loop mirror [4], and nonlinear amplifying loop mirror, etc., have been reported in operateion at high pump power. In addition, many devices or nanomaterials, such as semiconductor saturable absorber mirrors (SESAMs) [5], carbon nanotubes [6], graphene [7], [8], graphene oxide [9], [10], etc., have been employed inside the cavity of fiber lasers as the SAs to produce the mode-locked pulses. Although the SESAM has been widely adopted in PML-FLs for the generation of short and robust pulses, the fabrication and packaging technology are complex and expensive, and the operation bandwidth is relatively narrow.…”

The Q-switched pulse and mode-locked pulse were investigated in an all-normal dispersion Yb-doped fiber laser (YDFL) based on the topological insulators (TIs) with mixing of polyvinyl alcohol (PVA) to produce Bi 2 Se 3 /PVA film or deposition on the end facet of fiber to manufacture TI-compatible fiber. Through the dark Bi 2 Se 3 /PVA films with large nonsaturable loss, the YDFL was operated in the Q-switched state. The repetition rate and the duration of the Q-switched pulses increased and declined, respectively, with the pump power to show 2.2 μs duration and 137.8 kHz repetition rate at the highest pump power. Moreover, the mode-locked pulses, with a 16 MHz repetition rate and 380 ps pulsewidth, were generated at high pump power by using the light Bi 2 Se 3 /PVA film. By means of a Bi 2 Se 3 compatible fiber, through optical deposition of the Bi 2 Se 3 nanoplatelets on the end facet of the fiber, the mode-locked YDFL was generated at low-threshold pump power and revealed more stabilized operation state up to two hours.

“…To date, passively mode-locked fiber lasers (PML FLs) have attracted much attention because of their scientific interest, industrial application and biomedical diagnosis capability. Various modulated techniques including semiconductor saturable absorber mirror (SESAM) [1,2], carbon nanotube, graphene [3], grapheme oxide [4], nonlinear amplifier loop mirror (NALM) [5], and nonlinear polarization rotation (NPR) [6][7][8][9][10] have been exploited to generate stable ML pulses in fiber lasers. Although traditional stretched pulse fiber lasers have been demonstrated to produce ultrashort pulses, the highest pulse energy of this kind of laser system was limited to about a sub-nanojoule so as to prevent wave-breaking or multipulse generation [6,7].…”

With elongated cavity length, a 317 kHz low-repetition-rate rectangular pulse was demonstrated in an all-normal dispersion mode-locked (ML) ytterbium-doped fiber laser (YDFL) based on the nonlinear polarization evolution technique. As the pump power increased, the duration of the rectangular pulse broadened linearly without wave-breaking. At a maximum pump power of 240 mW, a rectangular pulse with a duration of 20.5 ns and highest pulse energy of 182 nJ was produced. Through an Yb 3+ -doped fiber amplifier with 4 W pump power, the energy of the rectangular pulse was further amplified up to 2.28 µJ. The duration of the rectangular pulse remained constant as the pump energy increased and revealed no pulse distortion under the maximum output energy.

“…For the generation of robust ultrashort pulse from PMFLs, various saturable absorbers, such as the semiconductor saturable absorber mirror (SESAM) [4], carbon nanotube [5], graphene [6], graphene oxide [7] and various topological insulator like Bi2Se3 [8] and Sb2Te3 [9], are investigated. Besides, the artificial saturable absorbers like nonlinear amplifying loop mirror (NALM) [10], and nonlinear polarization rotation (NPR) mechanism [11][12] etc., are extensively adopted based on the optical kerr effect.…”

In this work, we investigate the passive mode-locked Ytterbium-doped fiber laser based on the nonlinear polarization rotation technique. With the grating pairs inside laser cavity for the GVD compensation, the total cavity dispersion is operated within anomalous dispersion region. As the laser operates at fundamental mode locking, it generates 35 MHz repetition rate mode-locked pulse with 3.3 ps pulsewidth and the optical spectrum reveals obvious Kelly side. After adjusting the waveplate or increase the pump power, the 2 nd HML to 6 th harmonic mode locking (HML) is demonstrated in this laser. Besides, we also generated the bound states of multiple solitons whose separation of each pulse is about several tens of picosecond. The number of solitons and the separation between sequential pulses could be controlled so that it could be used in optical communication.,
