Summary: In this research, a soliton mode-locked erbium-doped fiber laser using Co3O4 as a saturable absorber (SA) in the 1.5-mu m region is proposed. Spherical Co3O4 nanoparticles embedded in polyvinyl alcohol were used to form a Co3O4-polyvinyl alcohol (PVA) film. Highly stable soliton mode-locked pulses were observed at 1558.86 nm with a 3 dB bandwidth, fundamental frequency, pulse width, and signal-to-noise ratio of 2.25 nm, 5.68 MHz, 1.24 ps, and 72.37 dB, respectively. The experimental results demonstrate that spherical Co3O4 nanoparticles exhibit good performance as a promising SA for creating soliton mode-locked fiber lasers.

Summary: We developed an erbium-doped fiber-based saturable absorber (SA) using niobium aluminium carbide (Nb2AlC) nanomaterial, which can generate stable mode-locked pulses. The SA was fabricated with polyvinyl alcohol (PVA) and the Nb2AlC nanomaterial, producing pulses operating at 1530 nm with a repetition rate of 1 MHz and pulse width of 6.375 ps. A peak pulse energy of 7.43 nJ was achieved at 175.87 mW pump power. This study not only provides design suggestions for SAs based on MAX phase materials but also demonstrates the great potential of MAX phase materials for generating ultra-short laser pulses.

Summary: In this study, we synthesized a Bismuth Selenide (Bi2Se3) saturable absorber (SA) and successfully generated two types of soliton pulses using different laser cavity configurations. These solitons operated at fundamental repetition rates of 23.3 MHz and 13 MHz, and exhibited Kelly sidebands and peak-dip sidebands, respectively. The addition of single mode fiber (SMF) split the soliton pulse into 44 pulses with bunched oscillation envelope and imposed peak-dip sidebands due to constructive and destructive interferences. The measured pulse widths were 0.63 ps and 1.52 ps for the solitons with Kelly sidebands and peak-dip sidebands, respectively. This research demonstrates the potential of Bi2Se3 SAs in generating different types of soliton pulses, with potential applications in optical communication and spectroscopy.
