Fig. 6, which contains a row cut from a more intensely exposed streak. In the center
of the beam, the durations were 35 ps at 2000 counts and 28 ps at 400 counts. In both
skirts, the duration was 23 ps. The total spread in pulse duration could be
interpreted as 5 ps of difference between the edge and center of the beam, with 7 ps
of saturation broadening at the beam center.
Fig. 6. Row cut from a more heavily exposed streak. The strong dependence of measured width on counts
is symptomatic of camera saturation.
We decided to define the FWHM for air-path streaks as the average of four
values measured from lineouts at varied counts. The selected lineouts were from
the unattenuated half of the streak. Figure 7 contains the values of FWHM from
the experiment that contained the greatest range in counts in the air-path streak. It
is a rather surprising result. The values of FWHM that were assigned by this
averaging did not vary strongly with camera counts, but the uncertainty did.
