Interaction of TEA CO(2) laser radiation with aerosol particles
Abstract:
Some effects arising from the interaction of TEA CO(2) 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-microm CO(2) laser radiation. The predominant charging effect at low intensities ( approximately 10(5) W/cm(2)) involves a loss of positive charge. Splitting of particle aggregates has also been observed.
