Abstract

The opportunities of the filament - induced emission spectroscopy method for analysis of elemental composition of aqueous aerosols in the atmosphere are estimated. Emission lines of chemical elements were excited by filamentation of femtosecond laser pulses (60 fs, 800 nm, 4.4 mJ) in the weak focus mode with the lens with 500 mm focal length in the aqueous aerosol. The limits of detection of aluminum, barium, and sodium in the aqueous aerosol are obtained.
