Abstract: Experimental the spectra studies of plasma generated in water aerosol under different focusing conditions (NA = 0.008, 0.02, 0.04) by short (8 ns) laser pulses with energies of 12.5, 25, 50 mJ were carried out. Time dependences of the signal-to-noise ratio for the emission lines of Ca II (393.4 nm), Ba II (455.4 nm), Na I (589 nm), Al I (396.2 nm) in the range from 0 to 6 $\mu$s were obtained.

Keywords: emission spectrum, laser plasma, water aerosol.
