“…Graphene has outstanding linear and non-linear optical properties, such as low threshold level of saturable absorption ( ∼0.7 MW cm −2 ), ultrafast recovery time (200 fs) and an ultrabroad wavelength independent saturable absorption range, which covers the wavelength range from the visible to the mid-IR [15,16]. Recent demonstrations of passively mode-locked or Q-switched fibre lasers focused on the operation in 1 µm [17,18] using 1560 nm continuous wave (CW) laser source and graphene saturable absorber (GSA). More recently, Jiang et al [2] achieved a laser with a short pulse duration of 760 ns and a repetition rate of 202 kHz by using graphene transferred to the high reflectivity (HR) mirror as SA.…”

A stable passive Q-switched thulium-doped fibre laser (TDFL) operating at the 1900 nm region is demonstrated by using a multi-layer graphene film-based saturable absorber (SA). The graphene is synthesised by electrochemical exfoliation of graphite at room temperature in 1% sodium dodecyl sulphate aqueous solution. Graphene flakes obtained from the process are mixed with polyethylene oxide as the host polymer to produce free standing composite thin film which acts as a passive Q-switcher in the TDFL ring cavity. At 793 nm pump power of 186 mW, the TDFL generates an optical pulse train with a repetition rate of 7.5 kHz, pulse width of 19.7 μs and a pulse energy of 66.6 nJ. A higher performance Q-switched TDFL could be achieved with the optimisation of the graphene SA and the laser cavity.

Hybrid Ytterbium/Brillouin Gain Assisted Partial Mode Locking in Yb-Doped Fiber Laser

We have demonstrated experimentally and theoretically that the hybrid ytterbium/Brillouin gain can contribute to partial mode locking in the high-loss ytterbiumdoped fiber laser. With only few cavity modes contained within the Brillouin gain curve, the dynamics of self-pulsing was not observed for the stimulated Brillouin scattering signal generated by each pump mode in the experiment. The results from two different experimental schemes show that both the Brillouin and ytterbium gains are required to support enough Brillouin pump and stokes cavity modes for partial mode locking. We also show that it is the coupling between the stimulated Brillouin scattering of the neighboring Brillouin pump modes that plays a direct role in the partial phase synchronization between different stokes modes. Furthermore, we proposed a theoretical model about the partially mode-locked laser dynamics. Based on the model, the numerical results agree quantitatively with the experimental ones. It is also found numerically that the extent of the phase synchronization can be enhanced by the cascaded stimulated Brillouin scattering according to the same physical mechanism.

“…It is relative easy and cheap to obtain such material, and wavelength independent. It becomes very popular to couple the graphene into the cavity to establish passive mode-locked or Q-switched fiber lasers [10][11][12][13]. Not long after the arising of Graphene saturable absorbers, Graphene Oxide (GO) began to attract researchers' eyes as well.…”

We review our work on a femtosecond erbium-doped all-fiber laser mode-locked with graphene oxide saturable absorber, which can be conveniently obtained from natural graphite by simple oxidation and ultra-sonication process. The laser directly generated 200 fs pulses at a repetition rate of 22.9 MHz. The stable passively Q-switched operation by graphene oxide saturable absorber in the 1 µm ytterbium-, 1.5 µm erbium-, and 2 µm thulium-doped fiber lasers will be demonstrated as well. These results are comparable with those of graphene saturable absorbers and the superiority of easy fabrication and hydrophilic property of graphene oxide will facilitate its potential applications for ultrafast photonics.
