Tailoring wavelength correlations in fiber-optical sources through nonlinear phenomena could drive many quantum optics applications. However, to date, such correlations have not been explored within fiber-optical parametric oscillators (FOPO), which are now widespread wavelength-agile sources. We experimentally investigate the real-time dynamics of a synchronously pumped picosecond FOPO with a combination of statistical tools using time-stretch spectroscopy. The study of wavelength correlations allows us to unveil particular spectrotemporal dynamics and correlation patterns. Specifically, we demonstrate that combining mutual information (MI) analysis and least-squares regression with large ensembles of shot-to-shot spectra allows to efficiently track energy transfers from pump to parametric waves. In addition, we show that tuning the FOPO parameters enables the shaping of spectral correlations to a certain extent.

We demonstrate a fiber optical parametric chirped-pulse oscillator (FOPCPO) pumped in the normal-dispersion regime by chirped pulses at 1.036 µm. Highly chirped idler pulses tunable from 1210 nm to 1270 nm with energies higher than 250 nJ are generated from our system, along with signal pulses tunable from 870 nm to 910 nm. Numerical simulations demonstrate that further energy scaling is possible and paves the way for the use of such FOPCPOs for applications requiring high-energy, compact, and low-noise sources, such as in biophotonics or spectroscopy.

We demonstrate for the first time, to our knowledge, an all-polarization-maintaining double-clad neodymium fiber laser operating in the dissipative soliton resonance (DSR) regime where stable mode-locking is achieved using a nonlinear amplifying loop mirror (NALM) with large normal dispersion in a figure-8 cavity design. The laser thereby generates square-shaped nanosecond pulses whose duration linearly scales with pump power from 0.5 up to 6 ns, with a maximum energy of 20 nJ. In addition, output pulses feature a remarkably narrow bandwidth of 60 pm along with a signal-to-noise ratio higher than 80 dB. This study then paves the way toward using such DSR-based sources for efficient frequency doubling in the blue spectral range.

We report on a passively mode-locked oscillator based on an erbium-doped dual concentric core fiber combining high normal dispersion and large mode area. This large normal dispersion laser generates long pulses with 30 ps duration and 0.17 nm spectral width at 1530 nm wavelength. The source delivers an average power of 64 mW at a repetition rate of 16 MHz, corresponding to 4 nJ energy. This concept opens up new degrees of freedom in the design of mode-locked fiber lasers.

We investigate the dynamical behavior of a self-pulsing laser under the influence of stimulated Brillouin scattering (SBS), a system which has previously been shown to favor extreme statistics. Using a laser model coupling a multi-Stokes Brillouin scattering process with the population inversion formalism for the gain and taking into account saturable absorption effects, we demonstrate that different statistical distribution types arise as the nonlinear interactions between the laser and higher-order SBS waves lead to the occurrence of high intensity short pulses. By taking into account up to five Stokes orders, we show that highly skewed statistics and pulses with extreme peak intensities can be obtained, allowing us to describe more accurately the experimental observations and to better apprehend the underlying physics. We also unexpectedly demonstrate that the acoustic noise does not affect the emergence of such extreme events.

We report for the first time a figure-8 all-PM mode-locked Nd-fiber laser operating at 927 nm in the dissipative soliton resonance (DSR) regime. This laser is based on a nonlinear amplifying loop mirror (NALM) and enables the generation of nanosecond pulses whose duration scales with pump power. Strikingly, the nanojoule output pulses feature a very narrow optical spectrum along with excellent noise properties.

We report on a mode-locked erbium-doped fiber laser delivering highly-chirped pulses with several tens of nanojoules of energy around 1560 nm and its exploitation to efficiently pump a fiber optical parametric oscillator (FOPO), thus enabling picosecond pulse generation around 1700 nm. The laser cavity features a high normal dispersion and mode-locking is sustained using tailored spectral filtering combined with nonlinear polarization evolution and a semiconductor saturable absorber. Numerical simulations show that the laser dynamics is governed by a strong mode-locking mechanism compensating for the large spectral and temporal pulse evolution along the cavity. In the frame of high energy picosecond pulse generation around 1700 nm, we then demonstrate that using highly-chirped pulses as pump pulses allows for the efficient tuning of the FOPO idler wavelength between 1620 and 1870 nm. In addition, satisfying noise characteristics have been achieved both for the Er-laser and the FOPO, with respective relative intensity noises (RIN) of −154 and −140 dBc/Hz, thus paving the way for the use of such sources in ultrafast instrumentation.

We report the tracking of single laser-induced shockwaves (SWs) using a real-time all-optical imaging setup based on amplified time-stretch dispersive Fourier transformation. SW propagation is encoded transversally on spatially dispersed ultrashort pulses at a frame rate of 80 MHz, and the technique allows us to record its evolution on μs timescales. We were then able to monitor the slowing down of a single SW and its reflection on a plane surface and also to perform velocity statistics and to evidence SW-to-SW fluctuations. This feasibility study proves time-stretch imaging to be a complementary and particularly adapted method to study SW dynamics and interactions and fast non-repetitive events occurring in laser ablation.

We report on the successful operation of a dissipative soliton fiber laser mode-locked with a bulk InGaAs-based saturable absorber mirror forming a resonant micro-cavity. Highly-chirped pulses with several nanojoules of energy are thus produced. Remarkably, the laser performances in terms of output power and amplitude stability are comparable to those obtained with their multiple-quantum-well-based counterparts. This letter suggests that this simplified approach for saturable absorber mirrors can be considered as a promising alternative regarding ultrafast optics applications.

We report the experimental observation of extreme instabilities in a self-pulsing fiber laser under the influence of stimulated Brillouin scattering (SBS). Specifically, we observe temporally localized structures with high intensities that can be referred to as rogue events through their statistical behaviour with highly-skewed intensity distributions. The emergence of these SBS-induced rogue waves is attributed to the interplay between laser operation and resonant Stokes orders. As this behaviour is not accounted for by existing models, we also present numerical simulations showing that such instabilities can be observed in chaotic laser operation. This study opens up new possibilities towards harnessing extreme events in highly-dissipative systems through adapted laser cavity configurations.
