“…In terms of performance, these numerical results are reasonably comparable with those previously published in [15] on SCG pumped by NLPs, in the SMF case. In general, the extension and profile of our numerical spectra are also quite similar to the experimental spectra reported in other works [18,55], using SMF as the nonlinear medium. It must be highlighted that moderate peak powers (~100 W) were used in these simulations to obtain such spectra using NLPs as a pump, an advantage over USPs that require peak powers as high as kW [9,22,41,42,47].…”

In this paper, we carry out a numerical study of supercontinuum generation (SCG) by propagating hundreds of noise-like pulses (NLPs), produced by a figure-eight laser (F8L) model, through different lengths of standard single-mode fibre (SMF). This work confirms the results of our previous experimental study (Lauterio-Cruz et al 2017 Laser Phys. 27 065107), highlighting the interest in using NLPs as a pump for SCG in cheap optical fibres. Using moderate peak powers (~100 W) we obtain broad and smooth SC spectra extending over hundreds of nm towards longer wavelengths. In order to simulate the fibre attenuation out of the telecommunication window, we propose a rudimentary approximation of the attenuation spectrum for SMF.

“…Noise-like pulses (NLPs) have attracted considerable attention due to potential applications in various fields, such as super-continuum generation [1], optical coherent tomography [2], nonlinear frequency conversion [3] and laser-induced breakdown spectroscopy [4]. Stemming from the interaction between linear and nonlinear processes, various mode-locking pulse behaviors can be observed in the cavity.…”

A noise-like pulse (NLP) is generated in an anomalous-dispersion passively mode-locked erbium-doped fiber laser using graded-index multimode fiber (GIMF) as the all-fiber saturable absorber (SA) for the first time. By splicing two sections of bending GIMF at both ends of a single mode fiber and optimizing the birefringence and nonlinear parameters, stable NLP mode-locking operation can be achieved within a wide pump power range. Meanwhile, the performances of NLP mode-locking have been analyzed experimentally by changing the length of the GIMF.

“…NLP has aroused intense research interests due to the characteristics of high energy, wide spectrum and low-coherence since it was reported by Horowitz et al for the first time in 1997 [17]. The NLP fiber laser has wide applications in the fields of optical sensors [18], supercontinuum generation [19,20] and optical coherence tomography [21]. In general, NLP has a nanosecond envelope and the interior of the envelope consists of a series of sub-picosecond secondary-pulses with random variations in terms of both intensity and width [17].…”

Pump-controlled flexible generation between dissipative soliton and noise-like pulses from a mode-locked Er-doped fiber laser

We experimentally investigate the alternative generation of dissipative solitons (DSs) or noise-like pulses (NLPs) from a passively mode-locked Er-doped all-fiber laser with 45° tilted fiber grating (45° TFG). The 45° TFG serves as an in-fiber polarizer for mode locking in the all-fiber laser cavity. Under the fixed orientations of the polarization controllers, flexible generation between DSs and NLPs can be precisely controlled by adjusting the pump power only. To the best of our knowledge, the total cavity length 4.92 m of our fiber laser is the shortest one among all of NLP fiber laser. We obtain the DS with 3 dB bandwidth of 20.4 nm centered at 1577 nm and the NLP with 3 dB bandwidth of 25.2 nm centered at 1574 nm. The fundamental repetition rate of the mode-locked pulses is 42.3 MHz. This DS-NLP switchable Er-doped fiber laser can be regarded as a multi-functional optical source for diverse practical and potential applications.
