Filamentation of Mid-IR pulses in ambient air in the vicinity of molecular resonances
Valentina Shumakova, Skirmantas Alisauskas, Pavel Malevich +8
Properties of filaments ignited by multi-millijoule, 90-fs mid-IR pulses centered at 3.9 μm are examined experimentally by monitoring plasma density and losses as well as spectral…
