Figure 3
Correlation plot between the X-ray intensity monitor and the transmission intensity of a Ce:YAG crystal. Before time 0 (blue trace) the Ce:YAG transmission is independent of the X-ray intensity. After time 0, when the crystal is pumped by the X-ray, the transmission intensity is directly correlated with the X-ray intensity. Large signals observable in the correlation plots can also be used to optimized other experimental parameters such as spatial overlap between the X-ray and optical laser. |
