Free-Space Nonlinear Beam Combining Towards Filamentation
Shermineh Rostami, Wiktor Walasik, Daniel Kepler +3
Multi-filamentation opens new degrees of freedom for manipulating electromagnetic waves in air. However, without control, multiple filament interactions, including attraction, repu…

Dramatic enhancement of supercontinuum generation in elliptically-polarized laser filaments
Shermineh Rostami, Michael Chini, Khan Lim +6
Broadband laser sources based on supercontinuum generation by femtosecond laser filamentation have enabled applications from stand-off sensing and spectroscopy to the generation an…

Effect of light polarization on plasma distribution and filament formation
L. Arissian, D. Mirell, J. Yeak +2
We show that, for 200 fs light pulses at 790 nm, the formation of filaments is strongly affected by the laser light polarization . Filamentation does not exist for a pure circularl…
