Paper Abstract

The aerosol attenuation of a near-ultraviolet laser radiation propagating through a simulated and controlled medium is investigated experimentally. Radiation from an excimer laser in an air-sea interaction simulation tunnel is utilized. Attention is focused on the measurement of aerosol profiles as a function of the X-axis above the water surface, water density in air, mean wind velocity in the tunnel, the difference between air and water temperature corresponding to various fog densities as well as the differential measurements of the total attenuation of the ultraviolet radiation passing through the medium. Examples of KrF and XeF transmittances for various granulometric distributions of water droplets are presented along with relationships between measured transmittances and liquid volume per unit air volume.
