(a) Pulse intensity correlation between the fast diode measurement of the summed-pulse intensities in each pulse (Inline graphic) and the PIPS diode signal Inline graphic for a time separation Inline graphic = 8.75 ns. (b) Histogram of the summed-pulse intensities (Inline graphic) distribution measured by the fast diode from 105 shots. (c) Two-dimensional cumulative histogram of the pulse intensity ratio of fast diode summed-pulse intensity and PIPS diode Inline graphic as a function of the PIPS diode signal Inline graphic from 105 shots. The color bar indicates counts. (d, e) Histograms and Gaussian fits (solid line) of the PIPS normalized pulse intensity of the pulse pairs Inline graphic for the two signal levels of Inline graphic indicated by the red and green areas in (c).
