Abstract

Some effects arising from the interaction of TEA CO2 laser pulses with individual aerosol particles are described. The time dependence of thermal radiation emitted from aerosol particles heated with pulses from a TEA laser is shown to be related to the size of individual particles and to the distribution of sizes within an aerosol. Charge and mass changes have been determined for single particles on absorption of 10.6-μm CO2 laser radiation. The predominant charging effect at low intensities (≃ 105 W/cm2) involves a loss of positive charge. Splitting of particle aggregates has also been observed.
