Sideband suppression of conventional soliton in Figure-9 passively Mode-locked fiber laser

Lei Liang et al.

Summary: This paper investigates the sideband suppression of a conventional soliton pulse through both experimental and theoretical approaches using a figure-9 passively mode-locked fiber laser. The sidebands of a conventional soliton can be suppressed by adjusting the polarization controller without reducing the output power of the soliton pulse. Three different spectral forms with varying degrees of sideband suppression are experimentally obtained and a theoretical analysis of the mechanism is presented. A theoretical model of the figure-9 passively mode-locked fiber laser is established based on a round-trip model, and the experimental results are confirmed by changing the phase difference induced by the polarization controller in the laser cavity. These findings have significant reference value in improving the spectral output and eliminating the sidebands of conventional solitons.

Plasmonic metafiber for all-fiber Q-switched cylindrical vector lasers

He Hua et al.

Summary: Metafibers, integrating metasurface at the optical fiber tip, provide significant optical coupling platforms for nanophotonics and fiber-optic communities. Here, a plasmonic metafiber is proposed to convert the fundamental mode to first-order mode in fiber, and an all-fiber Q-switched cylindrical vector laser is demonstrated using the metafiber. A polarization-independent mode conversion metasurface is designed and fabricated on fiber facet, achieving an efficiency up to 21% at 1550-nm band. By using the metafiber in an all-fiber laser, Q-switched azimuthally polarized beam (APB) and radially polarized beam (RPB) are generated with pulse durations varying from about 7 to 2 μs as pump power increases from 30 to 120 mW. The research provides a new strategy for integrating metasurfaces into all-in-fiber systems and offers a reliable route for constructing next-generation laser sources.

Generation of separation-locked bound solitons in a passively mode-locked all-fiber laser with a Fabry-Perot microcavity

Wenlei Li et al.

Summary: We report the generation of separation-locked bound solitons in a passively mode-locked all-fiber laser with a Fabry-Perot (F-P) microcavity. The observed bound solitons are directly generated from continuous wave without experiencing single-soliton mode-locking process. The numerical results are in good agreement with the experimental observations and confirm that the generation of bound solitons with locked separation is attributed to the F-P microcavity. This study provides a versatile method to generate several types of separation-locked bound solitons using F-P microcavity, which play vital roles in fiber sensor and optical information storage.

Tunable Dual-Wavelength with Twin-Pulse Dissipative Solitons in All-Normal Dispersion Yb-Doped Fiber Laser

Xiaojun Zhu et al.

Summary: A tunable dual-wavelength Yb-doped mode-locked fiber laser with two separated twin-pulse dissipative solitons (DSs) in the all-normal-dispersion (ANDi) regime is reported in this paper. By adjusting the polarization state of a Sagnac loop, the spectral ranges of the dual-wavelength can be tuned, while maintaining the pulse space between the twin-pulses. The twin-pulses can regress to a single-pulse as the pump power decreases.

Summary: In this study, fiber-based PbS quantum dots as a saturable absorber were studied for the generation of dual-wavelength ultrafast pulses for the first time. By introducing PbS quantum dots saturable absorber into an erbium-doped fiber laser, the laser was able to simultaneously generate dual-wavelength conventional solitons with central wavelengths of 1532 and 1559 nm and 3 dB bandwidths of 2.8 and 2.5 nm, respectively. The results demonstrate the potential application prospects of PbS quantum dots as broadband saturable absorbers for ultrafast laser generation.
