Journal ArticleDOI
Modeling of CW Yb-doped fiber lasers with highly nonlinear cavity dynamics.
Sergei K. Turitsyn,A. E. Bednyakova,Mikhail P. Fedoruk,A.I. Latkin,Andrei A. Fotiadi,Andrei S Kurkov,E.M. Sholokhov +6 more
TL;DR: The model is capable to accurately describe main features of the experimentally measured laser outputs such as power efficiency slope, power leakage through fibre Bragg gratings, spectral broadening and spectral shape of generated radiation.
Journal ArticleDOI
Multicolour nonlinearly bound chirped dissipative solitons
Sergey A. Babin,Evgeniy V. Podivilov,Denis S. Kharenko,A. E. Bednyakova,Mikhail P. Fedoruk,Vladimir L. Kalashnikov,Alexander Apolonski +6 more
TL;DR: It is demonstrated that intracavity feedback provided by re-injection of a Raman pulse into the laser cavity leads to formation of a coherent Raman dissipative soliton, which forms a two (three)-colour stable complex with higher total energy and broader spectrum than those of the dissipatives alone.
Journal ArticleDOI
Evolution of dissipative solitons in a fiber laser oscillator in the presence of strong Raman scattering
A. E. Bednyakova,Sergey A. Babin,Denis S. Kharenko,Evgeniy V. Podivilov,Mikhail P. Fedoruk,Vladimir L. Kalashnikov,Alexander Apolonski +6 more
TL;DR: The results demonstrate that the rising noisy Raman pulse (RP) acts not only as an additional channel of the energy dissipation destroying DS, but on the contrary can support it that results in formation of a complex of the bound DS and RP of comparable energy and duration.
Journal ArticleDOI
Inverse four-wave mixing and self-parametric amplification in optical fibre
Sergei K. Turitsyn,Sergei K. Turitsyn,A. E. Bednyakova,Mikhail P. Fedoruk,Serguei Papernyi,Wallace Clements +5 more
TL;DR: A new nonlinear self-action effect, self-parametric amplification (SPA), is presented, which manifests itself as optical spectrum narrowing in normal dispersion fibre, leading to very stable propagation with a distinctive spectral distribution.
Journal ArticleDOI
Generation dynamics of the narrowband Yb-doped fiber laser.
A. E. Bednyakova,O.A. Gorbunov,M.O. Politko,Sergey I. Kablukov,Sergey Smirnov,Dmitry V. Churkin,Mikhail P. Fedoruk,S. A. Babin +7 more
TL;DR: A significant decrease below the Gaussian probability has been experimentally observed for intensity fluctuations having value more than 2.5 of average intensity that may be treated as indication of some mode correlations.
