In order to solve the problem of unstable swinging amplitudes of the crane's boom and supporting points for moving heavy objects in the transportation and industrial industries, a pendulum system model with circular motion in the horizontal plane is

Operation states of multiple solitons (MS), noise-like pulses (NLP), and a special pattern of MS coexist with NLP have been observed in a passively mode-locked erbium-doped fiber laser. By increasing the pump power or adjusting the polarization state

International audience; We have performed a numerical simulation study of a hybrid regime of anomalous-dispersion-fiber lasers inwhich passive mode locking occurs simultaneously with the regime of regular undamped spikes induced by anintracavity satu

The formation mechanism of optical domains in multipulse fiber lasers was investigated. Optical domains consist of a square-shaped condensed phase of pulses derived from the slow evolution of gain. With the cross-gain saturation effect of wavelength-

Dissipative soliton resonance (DSR) is an efficient way to achieve high energetic pulses without wave breaking. In fiber laser, DSR operation manifests as square pulses emission. Based on this principle, we have experimentally demonstrated pulses in

Owing to its strong optical characteristics, graphene has emerged in the field of ultrafast lasers as a prominent saturable absorber. In this communication, we present a passively mode-locked Er:Yb doped double-clad fiber laser using a graphene depos

International audience; We report on the experimental observation of a color domain (CD) phenomenon in a dissipative soliton fiber laser. The CDs are constituted by a wavelength-dependent condensed phase of pulses in motion. Single CD, dual CD, and t

We report the generation of square pulses operating in dissipative soliton resonance region from a dual-amplifier figure-of-eight fiber laser. Pulses with tunable width in a range of 360 ns and energy up to 10 μJ are obtained.
