Soliton ratchetlike dynamics by ac forces with harmonic mixing.
The possibility of unidirectional motion of a kink (topological soliton) of a dissipative sine-Gordon equation in the presence of ac forces with harmonic mixing (at least biharmonic) and of zero mean, is presented. The dependence of the kink mean velocity on system parameters is investigated numerically and the results are compared with a perturbation analysis based on a point-particle represen...
متن کاملSoliton propagation and polarization mode-locking in birefringent optical fibres
In recent years much work has been devoted to the development of erbium-doped fibre lasers [ 1-91. because a broad zain bandwidth centred nearly I.54 urn. cegative group velocitv dispersion and tight confinement of optical field allow the exploitation of nonlinear optical effects for very efficient generatlon of ultra-short optical pulses. In the last few years several schemes of fibre soliton ...
متن کاملDissipative soliton and synchronously dual-wavelength mode-locking Yb:YSO lasers.
We experimentally demonstrate the dissipative soliton mode-locking operation of a Yb:YSO laser by using an all-normal dispersion cavity. Strongly chirped pulses are obtained with pulse duration of 9.3 ps at a repetition rate of 113.4 MHz. The central wavelength is 1082 nm with 3.1 nm FWHM bandwidth. A dual-wavelength synchronously mode-locking operation at central wavelengths of 1059.2 nm and 1...
متن کاملMode-locking of mobile discrete breathers.
We study numerically synchronization phenomena of mobile discrete breathers in dissipative nonlinear lattices periodically forced. When varying the driving intensity, the breather velocity generically locks at rational multiples of the driving frequency. In most cases, the locking plateau coincides with the linear stability domain of the resonant mobile breather and desynchronization occurs by ...
متن کاملStatistical light-mode dynamics of multipulse passive mode locking.
We study the multipulse formation in passive mode locking in the framework of the statistical light-mode dynamics theory. It is a many-body theory that treats the complex many-mode laser system by statistical mechanics. We give a detailed theory and experimental verification for the important case of multiple-pulse formation in the laser cavity. We follow and extend our former work on the subje...
