Spatial beam self-cleaning in tapered Yb-doped GRIN multimode fiber with decelerating nonlinearity
A. Niang, D. Modotto, A. Tonello +12
We experimentally demonstrate spatial beam self-cleaning in an Yb-doped graded-index multimode fiber taper, both in passive and active configurations. The input laser beam at 1064…
LIPSS on thin metallic films: New insights from multiplicity of laser-excited electromagnetic modes and efficiency of metal oxidation
Alexander V. Dostovalov, Thibault J. -Y. Derrien, Sergei A. Lizunov +6
Thin Cr films 28-nm thick deposited on glass substrates were processed by scanning low-intensity femtosecond laser pulses with energy well below single-pulse damage threshold. Two…
Hydrodynamic 2D turbulence and spatial beam condensation in multimode optical fibers
E. V. Podivilov, D. S. Kharenko, V. A. Gonta +6
We show that Kerr beam self-cleaning results from parametric mode mixing instabilities, that generate a number of nonlinearly interacting modes with randomized phases -- optical wa…
Dissipative soliton comb
Evgeniy V. Podivilov, Denis S. Kharenko, Anastasia E. Bednyakova +2
Dissipative solitons are stable localized coherent structures with linear frequency chirp generated in normal-dispersion mode-locked lasers. The soliton energy in fiber lasers is l…
Giant Coulomb broadening and Raman lasing on ionic transitions
A. A. Apolonsky, S. A. Babin, A. I. Chernykh +4
CW generation of anti-Stokes Raman laser on a number of blue-green argon-ion lines (4p-4s, 4p-3d) has been demonstrated with optical pumping from metastable levels 3d'^2G, 3d^4F. I…
