Abstract:

The results of experiments to measure the delay, temporal stretching, attenuation and spatial spreading of optical pulses in scale model clouds are reported. The model clouds consisted of diiodomenthanewater or paraffin oilwater emulsions maintained in a rotating scattering cell to prevent settling of the droplets. The optical pulses were 532 nm, 25 ps duration pulses generated by a frequency doubled, passively mode locked NdYAG laser and were detected with a 10 ps resolution streak camera. The measurements of the delay in the mean arrival time of the pulses due to multiple scattering are the first ever measured directly. Author
