The single-, dual- and triple-wavelength passively mode-locked erbium-doped fiber lasers are demonstrated with MoS2 and polarization-dependent isolator (PD-ISO). The saturable absorber is fabricated by wrapping an MoS2 around a microfiber. The intracavity PD-ISO acts as a wavelength-tunable filter with a polarization controller (PC) by adjusting the linear birefringence. Single-wavelength mode-locked fiber laser can self-start with suitable pump power. With appropriate PC state, dual- and triple-wavelength operations can be observed when gains at different wavelengths reach a balance. It is noteworthy that dual-wavelength pulses exhibiting peak and dip sidebands, respectively, are demonstrated in the experiment. The proposed simple and multi-wavelength all-fiber conventional soliton lasers could possess potential applications in numerous fields, such as sensors, THz generations and optical communications.

All-fiber passively Q-switched fiber lasers have been demonstrated by using graphene oxide (GO) Q-switcher for possible applications in telecommunication, laser processing, fiber sensing and medical community. The GO material was obtained through a modified Hummers method from expanded acid washed graphite flakes and it was embedded into a polyvinyl alcohol (PVA) film to form a saturable absorber (SA) device. The Q-switched pulse operates at 1563.3 nm with a repetition rate that can be tuned from 44.33 kHz to 61.77 kHz as the pump power changes from 39 mW to 96 mW. The highest repetition rate of 61.77 kHz is achieved at a pump power of 96 mW and it is observed that the Q-switched pulse produced maximum pulse energy of 0.054 nJ and pulse width of 5.57 ?s at 96 mW pump power.

In this work, a compact, stable dual-wavelength Q-switched laser with a multi-walled carbon nanotubes (MWCNTs) slurry as saturable absorber (SA) which is independent of any host polymer has been demonstrated. The MWCNTs slurry is fabricated and the peak shift is investigated using Raman spectroscopy.The passively Q-switched erbium-doped fiber laser (EDFL) oscillated simultaneously at 1532.32 nm and 1556.97 nm with 24.67 nm peak separation, at threshold and maximum input power of 26mW and 74mW respectively.By increasing the input pump power from 36 mW to 74 mW, the pulse train repetition rate increases from 25 kHz to 78 kHz, while the pulse width is reduced from 17.84 us to 5.24 ?s. The generated pulse produced maximum pulse energy and maximum peak power of 11.97 nJ and 2.05 mW, respectively at maximum input pump power. The recorded signal to noise ratio is about 62 dB and shows that the proposed MWCNTs slurry based SAis able to generate dual wavelength Q-switched pulse laser with high stability pulse.

The performance of a stable passive Q-switched Erbium Ytterbium co-doped fiber laser (EYFL) operating at 1532.5 nm is demonstrated using a multi-layer graphene film based saturable absorber. The graphene is synthesized by electrochemical exfoliation of graphite at room temperature in 1% sodium dodecyl sulphate (SDS) aqueous solution. Graphene flakes obtained from the process are mixed with polyethylene oxide (PEO) as the host polymer to produce free standing composite thin film which acts as a passive Q-switcher in the EYFL ring cavity. At 980 nm pump power of 44 mW, the EYFL generates optical pulse train with a repetition rate of 12.33 kHz and pulse width of 9.36 μs. The highest energy of 5.8 nJ and the lowest pulse width of 2.68 μs are achieved at the maximum pump power of 78 mW. Further increase in the pump power is expected to further improve both the pulse energy and pulse width.

A ring cavity multiwavelength Brillouin erbium-doped optical fiber laser （EDFL）based on the stimulated brillouin scattering effects and linear gain mechanism of erbium-doped fiber was demonstrated, in which single mode fiber was used as Brillouin gain medium and the Stokes signal was amplified by using the erbium-doped fiber amplifier, so that the laser can produce a stable multi-wavelength output at room temperature. Through the study and analysis of the position of the circular and coupler and the access mode of the coupler, we found that they both had influence on the output of the brillouin-erbium fiber laser. Then we have done some experiments at the Brillouin pump power of 14 dBm and the 980 nm pump power of 23 dBm, and single mode fiber length of 10km. The results showed that the access mode of the coupler affects the output of the brillouin-erbium fiber laser obviously. The detailed test results and the corresponding explanation were given.

Soliton mode-locked Erbium-doped fiber laser (EDFL) using single walled carbon nanotubes (SWCNTs) was experimentally demonstrated. In this work, SWCNTs was prepared by embedding into polyvinyl alcohol (PVA) as a saturable absorber. The laser generates a soliton pulse, which operates at 1570 nm region without any additional spectral filter as a 980 nm pump power is increased above the threshold value of 60 mW.  The output solitons have a pulse duration of 0.7 ps with a repetition rate of 18.98 MHz. At pump power of 130 mW, the pulse energy and peak power are approximately 0.032 nJ and 43 W.
