“…Because of the effectiveness of the passively mode-locked technique the formation and evolution of ultra-short pulses are fascinating subjects in nonlinear fiber optics. Diverse approaches such as carbon nanotubes [4]; topological insulators [5]; graphene nanopowders [6]; semiconductor saturable absorber mirrors [7]; nonlinear polarization rotation [8]; and nonlinear optical loop mirrors (NOLMs) [9], which act as saturable absorbers, are all employed to initiate passively mode-locked pulse lasers. Due to the high peak power, passively mode-locked fiber lasers are effective platforms for researching the nonlinear dynamics of mode-locked pulses.…”

A type of wave-breaking-free mode-locked dual-wavelength square pulse was experimentally observed in a figure-eight erbium-doped fiber laser with ultra-large net-anomalous dispersion. A 2.7 km long single-mode fiber (SMF) was incorporated as a nonlinear optical loop mirror (NOLM) and provided largely nonlinear phase accumulation and anomalous dispersion, which enhanced the four-wave-mixing effect to improve the stability of the dual-wavelength operation. In the NOLM, the long SMF with small birefringence supported the Sagnac interference as a filter to manage the dual-wavelength lasing. The dual-wavelength operation was made switchable by adjusting the intra-cavity polarization loss and phase delay corresponding to two square pulses. When the pump power was increased, the duration of the square pulse increased continuously while the peak pulse power gradually decreased. This square-type pulse can potentially be utilized for signal transmission and sensing.

Abstract. We investigate the generation of a chirped pulse in a single-mode, ring-cavity, erbium-doped fiber laser employing carbon nanotubes (CNTs) as a saturable absorber (SA). The pulse propagation is simulated using analytical methods to understand and quantify the role of multiple SA properties, particularly in the propagation dynamics of the laser pulse. The soliton solution is obtained on the basis of nonlinear effects, such as gain dispersion, second anomalous group-velocity dispersion, self-phase modulation, and two-photon absorption for a generalized nonlinear Schrodinger equation. The influences of the SA parameter in the range from 0.1 to 0.4 on the chirp, power, and width of the soliton are calculated. A stable, passively mode-locked fiber laser using CNTs as an SA is modeled. In addition, the power, width, chirp, and phase of the soliton pulses can be tuned by choosing suitable SA parameters.

“…Since the first demonstration on graphene mode-locked fiber lasers by Bao et al, 1 carbon-based materials of graphene [2][3][4] and nanoscale graphite 5,6 have been widely investigated in a fiber ring cavity as a novel saturable absorber (SA) for femtosecond/picosecond pulse generation. Compared with the semiconductor saturable absorber mirrors [7][8][9] and carbon nanotubes, [10][11][12] graphene as the saturable absorber shows some terrific properties, which includes lower saturation intensity, less nonsaturable loss, higher damage threshold, larger absorption (2.3% per single graphene sheet), and wavelength independence from visible to infrared due to its zero bandgap property.…”

Abstract. We have demonstrated the dissipative solitons generated in an ytterbium-doped fiber laser cavity using graphene oxide as the saturable absorber. The lasing light, centered at 1077.2 nm, has a 3 dB spectral bandwidth of ∼1.12 nm. Under different launched pump powers and appropriate polarization orientations, harmonic mode-locked of second-and third-order pulse trains have been achieved; the corresponding 3-dB bandwidth and pulse duration have been detected. © The Authors.
