“…When the pump power was gradually increased from 135.5 to 142.1 mW, 148.1, and 155.4 mW, the steady pulse trains with different repetition rates were obtained from the oscilloscope trace, as shown in Figure 3(a)-(c), respectively, which is the typical response of passively Q-switching operation. The pulse train obtained in this experiment is comparable with the Q-switched pulse train of similar cavity configuration using other SAs such as CNTs [16], SESAM [17] and graphene [18][19][20][21]. Figure 4(a) shows the oscilloscope trace of the Q-switched pulse trains at pump power of 148.1 mW, corresponding to Figure 3(b).…”

“…The average output power and the pulse energy were linearly increased with the input pump power. At the maximum pump power input of 195.3 mW, the maximum average output power is 0.038 mW, while the maximum pulse energy is 0.65 nJ, comparable to those Q-switched fiber lasers using graphene, CNTs and SESAMs as reported in [17][18][19][20][21]. The higher pulse energy could be obtained using a high-gain fiber (e.g.…”

This paper describes a demonstration of a passively dual-wavelength Q-switched ytterbium-doped fiber laser using a selenium bismuth-based saturable absorber. By utilizing a short-length photonic crystal fiber in a ring cavity and performing adjustments to the polarization state of an incorporated polarization controller (PC), we obtained a stable dual-wavelength Q-switched output at 1037.14 and 1037.69 nm, with maximum pulse energy of 0.65 nJ, shortest pulse width of 8.46 μs, and pulse repetition rate from 15.37 to 59.24 kHz. The Q-switched laser output consistently achieved high-power stability with a 0.8 dB maximum fluctuation over a period of 20 min.

“…In order to decrease the threshold of MI, we enhance the nonlinearity in a fiber laser cavity via long evanescent-field interaction length and strong mode confinement. To realize this, we use a long fiber taper deposited with reduced graphene oxide (reGO) [18][19][20][21][22]. The spontaneous XPMI is observed when pump power is set at 185 mW.…”

Abstract-Cross-phase modulation instability (XPMI) is experimentally observed in a fiber ring cavity with net normal dispersion and mode-locked by long fiber taper. The taper is deposited with reduced graphene oxide, which can decrease the threshold of XPMI due to the enhanced nonlinearity realized by 8 mm evanescent field interaction length and strong mode confinement. Experimental results indicate that the phase matching conditions in two polarization directions are different, and sidebands with different intensities are generated. This phase matching condition can be satisfied even the polarization state of the laser varies greatly under different pump strengths.Index Terms-Mode-locked fiber laser, cross phase modulation instability, reduced graphene oxide.

“…Recently, several groups found that the 3rd-order susceptibility of graphene is ultrahigh [6][7][8], so it can be utilized in nonlinear devices and systems. Luo et al observe the graphene-induced nonlineaer four-wave-mixing, which can be used for multiwavelength fiber laser [9]. However, the high nonlinearity has not been fully explored.…”

Abstract-A vector dual-wavelength rectangular-shape laser (RSL) based on a long fiber taper deposited with reduced graphene oxide is proposed, where the nonlinearity is enhanced due to large evanescent-field-interacting length and strong field confinement of a 8 mm fiber taper with a waist diameter of 4 μm. Graphene flakes are deposited uniformly on the taper waist with light pressure effect, so this structure guarantees both excellent saturable absorption and high nonlinearity. The RSL with a repetition rate of 7.9 MHz exhibits fast polarization switching in two orthogonal polarization directions, and the temporal and spectral characteristics are investigated. The results suggest that the long taper-based graphene structure is an efficient choice for nonlinear devices.
