Experimental investigation into interaction of femtosecond laser pulses with aerosol

This paper presents the results of experimental investigations into the interaction of laser pulses of femtosecond duration with aerosol having various composition (aqueous aerosol, dye solution with embedded nanoparticles), as well as with individual particles in the case of two-photon induced stimulated fluorescence. The acoustic method was employed to study the decay of the energy of the filament generated at different focusing, as well as the transmittance of the filament energy as it passed through the aerosol layer.
