Abstract
The dependences of the intensity of sodium emission lines on the time delay during filamentation of laser radiation of femtosecond duration in an aqueous aerosol with large (10 μm) and small (0.8-2 μm) particles was obtained. Emission lines (588.99 and 589.59 nm) were excited by filamentation of femtosecond laser pulses (60 fs, 800 nm, 3.8 mJ) in the weak focus mode with the lens with 500 mm focal length in the Na aqueous aerosol. It was experimentally established the optimal time delay for recording of the emission spectra of the filament in an aqueous aerosol with respect to the laser pulse.
