Optical breakdown from target reflected optical pulses in the Gemini laser system was studied. The retropulse fluence (or illuminance) leaving the amplifier was measured in terms of the energy entering the breakdown region and qualitative agreement but no quantitative agreement with theory was found. Particulates were observed on nucleopore filters through which gas samples were drawn.
