The influence of a plasma channel, created by a filament of focused UV or IR femtosecond laser pulse (λ = 248 or 740 nm), on the characteristics of another plasma channel formed by a femtosecond pulse at the same wavelength following the first one with varied nanosecond time delays was experimentally studied. The dependence of the optical transparency of the first channel and the plasma density of the second channel on the time delay was demonstrated to be quite different for such double UV and IR femtosecond pulses.
