“…However, the complex fabrication and narrow tuning range of SESAMs limit their practical usage. Recently, the effectiveness of single-wall carbon nanotubes (SWCNTs) [7][8][9][10][11] and graphene as SAs [12][13][14][15][16] has been demonstrated due to their ultra-fast recovery time, easy fabrication and broadband saturable absorption characteristics.…”

We have demonstrated an all-normal-dispersion passively mode-locked Yb-doped fiber laser using a graphene oxide/polyvinyl alcohol (GO-PVA) saturable absorber without surfactant, for the first time to the best of our knowledge. The experimental results show that the pulse duration of the mode-locked lasers varies from 191 ps to 1.68 ns, while the cavity round trip time changes from 24 to 458 ns, through the variation of the cavity length. In addition, the proposed passively mode-locked fiber laser demonstrates a maximum average output power of 539 mW with a laser cavity length of 94 m, and the corresponding single pulse energy reaches 0.429 µJ. The proposed mode-locked fiber lasers with large chirp pulses may find potential applications in fiber chirped pulse amplification systems for micromachining, material processing and diagnostic applications.

“…SWCNTs have significant advantages over SESAMs because they can be easier fabricated, have faster recovery time, and wider operation range of the wavelength, which makes them ideal SAs for realizing all-fiber Q-switched lasers. [10,[18][19][20][21] Up to now, there have been many reported works on applications of SWCNT materials as SA to achieve mode locking. [10,[19][20][21][22][23][24] However, there are only a few papers to obtain Q-switched pulse trains in the Yb-doped fiber lasers.…”

Different from the parameters of fixed mode-locked fiber laser, [24][25][26] the repetition rate of the Q-switched fiber laser is tunable by varying the pump power without pulse breaking.…”

An all-fiber laser using a single-walled carbon nanotube (SWCNT) as the saturable absorber (SA) for Q-switched operation in the 1031 nm region is demonstrated in this work. A lasing threshold as low as 17 mW was realized for continuous wave operation. By further increasing the pump power, stable Q-switched pulse trains are obtained when the pump power ranges from 38 mW to 125 mW, corresponding to repetition rate varying from 40.84 kHz to 66.24 kHz, the pulse width from 2.0 µs to 1.0 µs，and the highest single pulse energy of 40.6 nJ respectively.

“…Yue et al observed dual-wavelength DS in a mode-locked figure-eight fiber laser operating in the net-normal dispersion regime [11]. Li et al demonstrated 12-nm tunable DS operation, mode locked by single-walled carbon nanotube (SWCNT) absorber [12]. However, the invisible birefringence-induced bandpass filter in [10]- [12] depends greatly on the precise parameters of the laser cavity to achieve wavelength variation operation, which make it difficult to assess the effects of filter parameters on the DS operation.…”

We report a wavelength-switchable single-polarization dissipative soliton (DS) mode-locked fiber laser using a chirped fiber Bragg grating (FBG) for spectral filtering. The chirped FBG, when inserted into the ring cavity, provides a stopband from 1045 nm to 1057 nm, which is used for spectral filtering in this all-normal-dispersion mode-locked Yb-doped fiber laser. The combination of the chirped FBG and the Yb gain profile help the formation of the DS. The laser delivers wavelength-switchable and polarized (28 dB) DS of 6.1 nJ and 29 ps at 1032 nm, and 4.3 nJ and 24 ps at 1068 nm, respectively. To the best of our knowledge, this is the direct proof that a bandpass filter is not indispensible to achieve stable DS in ps fiber lasers.
